Hi Swedebugia,

I did not notice a PEG parser has been added. How did you notice this?
Maybe there is another blog for new additions to Guile?

Do you know a good text, which explains differences between the
different approaches to parsing? For example, what is the difference
between PEG parsing and parser combinators? There seems to be a whole
jungle of approaches to parsing out there, including parser generators,
which I believe take a grammar of certain kind and produce a parser from
that. I am never sure what languages I can parse using what approach.

Thanks anyways!
