:call extend(adict, bdict)
This extends adict with all entries from bdict. Duplicate keys cause entries

Note that the order of entries in a Dictionary is irrelevant, thus don't
expect ":echo adict" to show the items from bdict after the older entries in
adict.
Weeding out entries from a Dictionary can be done with |filter()|: >
