Having names not leak from listcomps and genexps is a good thing.
Having names not leak from try/execpt blocks is a necessary thing.
Having names not leak from if/else or while is confusing and irritating: there is no scope there, and at least 'while' should be similar to 'for' which also does a name binding and does /not/ unset it
at the end.

I would find the 'as NAME' portion very useful as long as it wasn't shadowing nor unset.
