Hi,

It's not clear to me from the documentation whether it's possible to define lexemes in terms of other lexemes.

E.g.

[0-9] "DIGIT"
[a-zA-Z] "LETTER"
{LETTER}({LETTER}|{DIGIT})* "ID"

Is this Lex feature supported by grmtools?

Thank you.

It's not supported. I would not object to a PR which added it!
