Lib/email/*.py are fond of using
EMPTYSTRING = ''
and within the code:
 EMPTYSTRING.join(...)
instead of just writing:
 ''.join(...)
They should just do the latter. It'll avoid a name lookup and look less silly to people reading the code. ;)

I've always wondered why the code did that. If Barry doesn't have a good reason for it, I'll refactor it at some point.

A long time ago, Tim (IIRC) expressed an opinion that using the variable makes
the code more readable. After having seen so much code that uses the string
literals over the years, I wholeheartedly agree with that opinion.

Good enough for me. I personally don't find it to be easier or harder to read with the names, so let's keep them.
