I didn't even know about `pmatch'. Is it supposed to be equivalent
to `match' (except that outer quasiquote, that is)?

With the caveat that I don't have much of a stylistic feeling for
Scheme, I'd clearly prefer `match': the writer has the choice of
quote or quasiquote, as appropriate to the case -- and the reader
sees what's going on (after all, quote and quasiquote are "low
weight" primitives: everyone more or less knows what they do.

But perhaps I misunderstood what you're after?
