I kinda assumed that parsers were being passed as constructor arguments
to other parsers anyway. I don't know enough about your approach using
the >> operator.

Right. It would be impossible to construct a grammar with the skip
parser as the last parser. I suppose you could have two versions of the
skip parser, one that returned the value of the next parser, and one
that returned the value of the previous.

Ick. Maybe this idea of mine isn't quite the right fit for your approach...
