Having "`foo`" mean str(foo) and having "'foo'" meaning "'foo'" seems pretty
confusing to me.

Backticks are awkward, hard to find on the keyboard, and hard to visually
differentiate from regular single-quotes.  I strongly dislike using them.

Then again, I never *would* use them, even if this proposal passes, because it
seems *much* clearer to me to use "%s" % foo

And the thought of reading through a string with 50 or more embedded expressions,
exactly the situation that this proposal is being recommended for, and trying to
keep straight what's text and what's code, gives me the willies.
