Guys,
Sturla's original email was quite subtle, but you may have missed that
he is proposing this as a joke PEP for April Fools Day, a bit like the
introduction of GOTO or the retirement of Guido:

http://legacy.python.org/dev/peps/pep-0401/
As a joke, it pokes fun at Apple's recent "goto fail" security breach.
Unfortunately the Python C source code apparently uses exactly the same
"goto fail" idiom, although hopefully not as poorly as Apple did.
