RE: "Recursive parsing"

[Xinan Tang]

Hi Alfonso

  Indeed recursive grammar parsing mixed these two things:

   First, it has to support multiple grammars like http and html and
javascript.

   Second, each grammar parser must be "pure" so that it can be called
in a reentrant way.

Thanks

Seems like you are talking about two different things here - multiple
grammars (which is doable with the "prefix" options), and pure
re-entrant
parsers. ?
