of course, this conflicts with the need to embed a literal ")" within a
sub-format. The simplest option for this would be to either allow %) as
an escape, as with %%. Even simpler, of course, would be %x29, but this
seems needlessly obscure. The only objection I have to %) is "It's
ugly". To me, %(format: "this is a paren: )") is easier to read, but
that would just be moving the problem around, adding the necessity of
the just-as-ugly-or-moreso %", or alternatively C-style \" and \\.
So I think that %) will be the best option.
