Directly Depends On Private Interface of
An "index" value remembers the lookup of a string in a table of strings.
Unless Object Types change a lot, the routines SetIndexFromAny and UpdateStringOfIndex do not need to exist. The object type is a caching one only, saving a table lookup result. There are no pure "index" values.
Tcl_WrongNumArgs is piled high with hackery, special cases and ugliness to bend it into useful service for ensembles, and possibly Itcl command variants as well. Surely a do-over with a clear vision of the support task from the beginning could be better.
The completion codes extractor might be good public.
There's no need to worry about INT_MAX restrictions here. These tools are for looking up in small tables of small strings via linear search. No need for major sophistication here.
