     Yes, I have had the same goal for some time.
     
     The global variables token, tokval, tokid, tokstr want to be
     encapsulated in a structure too.  tokid and tokstr should
     probably be merged somehow.  Some generalization and
     orthogonalization (if that's a word) is warranted.

Maybe I'll start looking at that when I get some time.

BTW, is there a reason why comments are dealt with in
src/language/command, instead of being filtered out by the lexer ?
