Interesting. I'll have to ask for more details on why.

+1. Personally I associate PEG with a parser that includes a
__distributed__ lexer inside, which gives the advantage of having
to check less alternatives at each step (that's similar to
deterministic parsing). If lexer is separate, it seems to be more
difficult to scan for only a subset of possible tokens.
