Congratulations for the topic and the interesting outline.
I look forward for the talk.

Thank you Stephan for mentioning Parse::Eyapp. I thought none paid previously attention to it :-(

Parse::Eyapp is fully compatible with Parse::Yapp. It fixes a few bugs that were in Parse::Yapp and -sure - it introduces new ones :-)

Furthermore, Parse::Eyapp extends Parse::Yapp with concepts similar to those found in Parse::RecDescent: autoactions, automatic generation of trees, etc.

There are, however, a few new functionalities: Translation Schemes and a Tree Transformation language to mention two.

If you need any assistance with the module I will be more than glad to help. Have a look at the examples directory inside the distribution. Also, there is a brief tutorial at
