[antlr-interest] mutual recursion in tree grammars

[Matthew Wilson]

Hi,

I was wondering why I'm getting the mutual recursion error in my tree
grammar (antlrworks 1.4.2).  Why would left recursion (mutual/indirect or
direct) matter at all in a tree grammar?  (How could there be referential
cycles in the tree?)

Thanks,
Matthew Wilson
