 Why does Test_invalid_sid() not work in the GUI?
 
-Making everything work:
-- Should :const work the same as in legacy script?
-  Or should it work like in Typescript: only the variable is fixed, not the
-  value itself.
-  Then use ":const!" to also fix/lock the value?
-  Typescript uses "as const", which is weird.
-  Alternative:  const var = <const>value
-      looks quite strange quite verbose
-      But can be used in several places:
-	    SomeFunc(<const>[1, 2, 3])
-      In Vim this basically means "lock this value".
-      How about:
-	    SomeFunc(<const>[[1], [2], [3]])  # are sub-lists immutable?
-	    SomeFunc(<const>myList)  # is myList mutable afterwards?
