Oh! That's Gmail's check spelling fault, sorry.
I meant: XTreams was borned in Pharo (not burned :)

XTreams is primarily a generalized stream/iterator framework.  It
contains PEG parser generation facilities, which I assume might use
XTreams. If not the PEG parser stuff could be separated.
Nikolay, what you write is interesting but too terse for me to
understand. If I understand you right you mean that OMeta goes beyond
the PEG parser in XTreams and PetitParser (L. Renggli) and Helvetia (L

In which ways does OMeta go beyond these other tools?

Again, I just could repeat, OMeta is not yet another tool, like PEG parser stuff, that could be founded in XTreams, Helvetica or PetitParser and others. It is a language, furthermore it is an object-oriented language for pattern matching. And it is based just on a variant of PEGs, which have been extended to handle arbitrary data types.
Thinking, that I couldn't say better then it is written on the author's site and his paper (http://www.tinlizzie.org/~awarth/papers/dls07.pdf), how OMeta goes beyond.


AND: Of course very welcome that you run for the board.
