Ter may be completely under water at the moment, but the "synpreds in
loops" issue has been raised as an ANTLR 3 design concern and one that
will probably be addressed. Right now, you can use synpreds in
recursive definitions, but not in loops. That rules out an important
class of refactorings: it is important that logically equivalent
constructs actually have the same behavior!
