[[ 0 == [[:IDENT:]]## ]]; print $?

That's fine. However, it also accepts 0[a-z]:
[[ 0q == [[:IDENT:]]## ]]; print $?
0
Shouldn't it be defined something like:
(<->|[A-Za-z_][A-Za-z0-9_]#)? So that it accepts $0, and also var0? but not
0var?

[...]
No, [:IDENT:] that you can use inside [...] is just another
character class, it can only match a single character.
Remember you can do things like `[[:IDENT:],.+[:blank:]] for
instance to match on a character that either
- classified as IDENT
- clsasified as blank
- ,
- .
