Yes, that makes even the capitalized "CON" issues go away. It's not a
one-to-one mapping, though ("foo-" and "foo_" map to the same entity).

foo_ would map to foo__, and foo- would map to something else.
(foo- as we do not rewrite dashes, yet?)

Ah, OK, I took your:

  [A-Z]  -> _[a-z]

to mean "A-Z becomes a-z, and everything else becomes underscore".

If you mean a real one-to-one mapping that allows a-z and only a few
safe metacharacters, then yeah, that's what I was thinking, too.

quoted

If we want that, too, I think something like url-encoding is fine, with
the caveat that we simply urlencode _more_ things (i.e., anything not in
[a-z_]).

Yeah I think we need more than url encoding now.

If you take "url encoding" to only be the mechanical transformation of
quoting, not the set of _what_ gets quoting, we can still stick with it.
We don't need to, but it's probably no worse than inventing our own
set of quoting rules.
