What about:

   o Beautiful is better than ugly
   o Explicit is better than implicit
   o Simple is better than complex
   o Readability counts
   o Special cases aren't special enough to break the rules
   o Errors should never pass silently

?

And most importantly:

   o In the face of ambiguity, refuse the temptation to guess.
   o There should be one -- and preferably only one -- obvious way to
do it.

?

So, what's the one obvious right way to express "foo\zbar"? Is it

   "foo\zbar"

or

   "foo\\zbar"

And if it's the latter, what possible benefit is there in allowing the
former?  And if it's the former, why does Python echo the latter?
