Pegasus - PEG grammar nimbleparsec generator

Thanks to @ityonemo for the library and @tj0 for bringing this up the forum. It sure looks like a better way than long indecipherable regular expressions. I have two questions once I start exploring:

  1. are there examples of how post_traverse work? (My attempts have only yielded some obscure CaseClauseError)

  2. I noted that there is a Pegasus.Components module. How is this supposed to be used?
