I don't know what you mean by "burned in Pharo", but XTreams was 
originally written in VisualWorks and then ported to Squeak/Pharo.

Well, this is one of my concerns with OMeta (besides the really bad 
performance compared to other PEG implementations). It's a language which 
is not smalltalk. IMHO PetitParser and MEPS are better from this POV, 
because they're DSLs inside smalltalk. This means that existing tools can 
be used with them out of the box.
