* Basic methodology here.
*
* The number of members in an aggregate is equal to the number of initializer parameters it takes less
* the number of empty base classes it has. In simple terms, this would be `init_terms< T > - empty_bases< T >`,
* However, it's not that simple. To do that the easy way, one might need get `std::tuple< InitTerms... >` and then compute
* which terms were bases. Now that gets a bit complicated, as in C++ one can't just directly get a tuple of initializer
* arguments (portably) to scoop out the arguments and analyze them one-by-one. One can, however, constrain the arguments
* one-by-one in templates. Those constraints cannot directly leak out the types they conclude, as that requires side
* effects. (Yes, template-friend-injection can be used here, but these mechanisms are extremely delicate. They're
* not really portable. Further, the way that constraints get instantiated for matching is prone to complications.)
*
* Instead, a side-stepping approach is required. It's trivial to ask: "Can this object be constructed from these
* N adaptive types, where the first one is constrained to be a base class of your object's type?" If yes, then
* this proves a (likely) empty base. One can just recursively iterate through more an more constrained adaptive
* types until the first non-base type is reached. At this point, there are no more than that many base classes.
*
* There may actually be fewer base classes, however. Consider:
*
* ```
* struct SneakyBase {};
*
* struct Complicated : SneakyBase
* {
* SneakyBase member;
* };
* ```
* In that case, a constrained adaptable argument would see two base types. Here is where a bit of C++ trivia and
* knowledge comes into play. C++ forbids repetition of a base class's type. Therefore the sequence of base classes
* cannot have repeats. The solution is to perform a nested exploration of instantiations of `checker` types which
* has each descent disable casting to `std::is_base_of_v` types which already have been expanded. Thus whatever
* count this expands to, it will be the correct empty-bases count. Then that count can be subtracted from the
* initializer list count.
*
* Note that this will not work with types that have non-empty bases, but those types cannot be decomposed,
* anyhow. Such types cannot have C++17 reflection performed on them.
*
* For the moment, computing a deep-dive on constrainted adaptable arguments is skipped. It's a lot more
* complicated than just counting empty bases. As long as the first actual member is not also a base class,
* this technique will work.

/*!
* Deconstruct an aggregate object into a tie-based tuple pointing at its members.
*
* C++17's primary new reflection-oriented introduction is Structured Binding Declarations.
* What these let one do is to introduce a set of named variables that bind to each member
* of a (raw aggregate) `struct` in turn. This leads to some very interesting forms of
* "reflection" about what a user defined type is made of. Combined with the `std::is_aggregate`
* trait function and a way to determine the number of member objects, this provides a
* powerful new way to inspect any type.
*
* Structured Binding Declarations can also be used with arrays or types which implement a subset
* of the `std::tuple` interface. Those cases are not as interesting. We've always had the
* ability to inspect arrays via templates -- simple deduction operations work for that. And
* C++11's `std::tuple`s are already inspectable by their nature and types which implement a tuple-like
* interface are also easily inspected by pre-C++17 means.
*
* The most important thing C++17 Structured Binding brings to the language is the ability to
* (at compiletime) programmatically inspect any structure's members -- to learn their types,
* and with a bit of special effort, to learn their offsets. The names of those members are
* hidden, but their types are available, as is a way to work with all of them at once. Any
* Structured Binding is sufficient to do this -- one need only give a new name for each member of
* the type. `auto &[ a, b, c, d ]= someStruct;` is all that is needed and one has already performed
* an interesting feat of rudimentary reflection on the type `someStruct`. By loading those values
* into a tuple (by reference), by code such as `std::tie( a, b, c, d )`, a programmer can provide
* an anonymized, distilled reflection of the contents of that `struct`. This said, a library function
* which can decompose any `struct` into such a tie is very useful. `tuplizeAggregate` is exactly this.
*
* This function contains a pre-built set of such decompositions for structs of various sizes. C++17
* does not permit arbitrarily sized Structured Bindings, and so a limit had to be placed. The limit
* is fairly generous, however. If an aggregate size which is greater than the pre-build maximum is
* provided, then the compile will fail on a `static_assert` indicating this.
*
* Unfortunately, as a declaration syntax, the number of members in a `struct`'s body cannot be inferred
* through SFINAE by this means. Normally the user must explicitly provide the number of member
* variables. However, combined with a pair of C++11 features (based upon variadic templates and
* aggregate initialization syntax) we can infer the number of memmber values via a set of helper
* templates (which can also be called directly.)
*
* This kind of reflection into an aggregate type can prove very useful. Code generators for
* serialization, conversion tools, universal utility functions, and much more can all be built in
* C++17, today, using this kind of reflection! There's no need to wait for C++23 or beyond when
* static reflection is added to the language. A great deal of desired reflection use cases can be
* attained today. One just need write some code generators in terms of `std::tuple` and `std::tie`,
* then make any overloads (perhaps using ADL hooking tricks) which call `Alepha::Reflection::tuplizeAggregate`
* and pass that result to the general tuple form. For serializers and such, other techniques such as
* `boost::core::demangle( typeid( instance ).name() )` can be used to get nice names for types when
* implementing universal serializers. In fact, this can be used as a crutch for serializing more
* complicated user types (with private data and such). Those types can produce an aggregate "view"
* of what they must serialize or deserialize, and then they can hand that view off to such code
* generators. And, of cousre, this need not apply just to serialization.
*
* @param agg Aggregate instance to decompose into a `std::tie` based `std::tuple`.
* @tparam aggregate_size The number of members in the aggregate argument `agg`'s definition.
* @tparam Aggregate The type of the aggregate to decompose.
