This leaves us with a few options:
5. Reuse/Abuse Num(object) for arbitrary constants. AFAICT, this should work out of the box.
Eek. It *does* seem like Num would work out of the box, but would this be a good idea?
No. I suggested it just for completeness.
What about *replacing* Num with Const? Might make optimizations specifically for numeric values slightly hairier, and semantically I think they might be different enough to warrant separate AST nodes despite the similarity in implementation at the compiler level.
I think they should be separate. Const would be a mere addition; for compatibility with other uses of the AST, that's actually better than simultaneous removal of Num. Regards, Martin
