Two problems I found copy/pasting grammars from standard docs:
- Repititions (*) were prefix instead of postfix
- "\" had to be escaped to "\\"
I still wonder about debugging techniques, though.

I used Xtreams because I wanted to copy/paste the grammar from the spec
instead of rewriting it in Smalltalk. I don't think that is possible in PP

Yes, there's some kind of bootstrapping process but I'm not clear how it
works and haven't found any documentation.

Hi,
If you are looking for PEG parsers, you can also try using PetitParser as it
comes with several debugging and inspection tools.
