Not likely.  It is possible that the latter spelling would make it possible for
Py3.0. eliminate list comps entirely.  However, they are very popular and
practical, so my bet is that they will live on.

The more likely change is that in Py3.0 list comps will no longer expose the
loop variable outside the loop.
