Eric,
        the attached file exibits a problem with (I think) display_expr:
The second line in main() fails. But if you comment out the definition of META_EXPR(plus,left,...) and replace it with the one
just below it and presently commented out then everything is fine.
Seems like display_expr is not appy with function applied to more than one argument.

Unless there's something stupid in my code.

Regards,

        Maurizio
