I like the patch. please commit it. I have a tiny suggestion. Sometimes is 
very useful to associate some description to the token. For instance you may 
want to associate the string ';' to the token SEMICOLON. This is very useful 
when reporting errors. In general you want to use the token description and 
not the token id in the error message (e.g. ';' not SEMICOLON).

so how about you change a bit the patch so we can write things like
%token SEMICOLON = ";"
%token ID "identifier"
...
