"P" for "Parser". The symbols are used past the lexer, but are isolated
to other places in the parser, and are (or should be) stripped out

If the lexer/parser should have postfix qualifiers, let's use postfix
for other naming conventions too (or switch everything to prefix, but be
consistant in the conventions).
No problem with qualifying the names, though you have likely overstated
the case for it; "fairly amazing" after 6 years of use on over a dozen
platforms probably qualifies as a good test of reality and we aren't
quite to the point of having to invoke miracles and magic to explain why
it works ;)
In any case, we would certainly be open to accepting patches for the
limited number of cases Katherine has identified, and would welcome
patches which are more comprehensive if they were available.
