[Python-Dev] PEP 572 and assert

Indeed -- this new feature makes it easier to affect the local scope in all
sorts of new places. It was decided that the additional complexity is worth
it to make the language more expressive, and it was also decided not to try
to "lock down" this new feature to only "appropriate" places.

Hmm --- not sure if it's PEP-worthy, but I'd sure love to see the community
make a strong stance that:

asserts are for tests, and only for tests

Which doesn't necessarily mean that assert statements only exist in test
code (though I personally follow that practice), but it does mean that
assert statements, wherever they live, should not be counted on at run
time, ever.
