Okay, yeah, I'm trying to do complicated things. But without getting
into my entire list of parse rules and asking you to do my work for me,
have you ever seen an exception like this before? When I try a certain
variation of my parse rules, on certain input, I get this exception from
parslet, which I was not expecting (just including the first part of the
stack trace):
ArgumentError: wrong number of arguments (1 for 0)
