I have seen many times here at PerlMonks that you pretty much favor -MO=Deparse. So it might be interesting to you that, as a first step of writing the Perl 5 to Perl 6 converter, Larry is working on parsing Perl to XML. The idea is to use the XML representation to turn it back to Perl 5 (to verify the correctness of the parser), and then to any other target languages. So it would be of similar functionality to -MO=Deparse, but it would be more correct I think.

Somehow, someone should convince Larry to release his code to let people to play around with it...
