Making a wiki application using Xtreams PEG grammars (i.e. PEGParser class >> grammarWiki) was hard. I had to figure out how to write an actor subclass to PEGActor.

Extending PEGWiki’s wiki grammar to include videos from Wistia [1] and making the videos is trivial compared to me trying to understand Michael and Martin’s agglomerations of blocks within blocks with stack arguments constructed by pragmas as single values in a dictionary.
