Pythoscope, the unit test generator

Comment 2 for bug 462849

Tracked it down. astbuilder can't handle the (new in python 2.7) multiple context managers with one statement described here [http://docs.python.org/dev/whatsnew/2.7.html#other-language-changes]

So it wont be a major problem until 2.7.

I'm marking this defect as "Invalid" to reflect that.

Maybe testing pythoscope against unreleased python code wasn't the best idea :)
