I see.

Wait, actually, I realized it was my own error. My test function was
using nonterminals, but I had only done (define grammar-string ....),
not (define-grammar grammar-string). I think the generated code tried
to call the nonterminals that should have been there, and threw an
error when it didn't find them.
The peg matcher is really awesome. I am glad to be able to use it soon.
