random, possibly clueless thoughts as i look at this: yes, transform rules by type would be nice! not sure what that means about having to generate a module within a macro, though (for namespacing).
do you parse strings or streams? (or both?) i know nothing about julia streams, yet, but i imagine streams would make it easier to abstract away nasty book-keeping for error reporting (line number etc). do you have any support for error handling? why aren't any of your type contents typed? can julia infer that from use? if not, it will have a big impact on speed and memory use, i would guess. even better if they can be immutable. thanks, andrew On Saturday, 31 May 2014 21:10:37 UTC-4, Abe Schneider wrote: > > I should add that PEGParser's code is fairly new and untested (besides > having an uninspired name).
