My comments had the wrong tone. I completely agree with the idea and your comments above. I too want an AST. I just don't want to see this part of Bison destabilized for an extended period. If we can't find a series of stable refactorings, perhaps we can find some temporary separation similar to push.c and yacc.c. _______________________________________________ [email protected] http://lists.gnu.org/mailman/listinfo/help-bison
