How long is long?

900 nodes in the AST seems to be the limit for the type of method SmaCC generates (cascading ifTrue:ifFalse:).

Other limits exist (number of literals, for example). Unless you generate automatically some code, it's hard to hit them. Once you generate automatically, it's easy to hit them :P

Now, the point is to see all that as a stream, cut methods at
appropriate places and compile code under a WAComponent subclass.

Yes. But then you need some kind of syntax to mark the start of a method. Change sets and dolphin packages use !! markers.

I don't know about SmaCC but I think I can do something with PetitParser
and Smalltalk compile:

It's all done with RBParser. Since you're parsing Smalltalk, it's easier to do it that way (and probably a bit faster). And you're also playing with the AST, so you want to fall back to a well defined API for that AST (and visitors, and the like).

Extending RBParser with a scheme to parse multi-methods files could be convenient.

Unless you fall back on a variant of a changeset.
