Which Perl module for parsing ambiguous grammars?

[MacTommy]

I am looking for a module that can parse ambiguous grammars and that gives me all the possible parse trees. Also, it should have 'actions'.

I looked at Parse::Yapp and Parse::RedDescent which both look great, they have actions, but neither will give multiple solutions in case of ambiguity (or will they?!?).

I saw Parse::Earley but it doesn't support actions.

Any other suggestions?
Any help is really appreciated!
