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

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

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.
