It sounds like list comprehensions are being implemented
using genexps behind the scenes now.

Is this wise? In a recent thread, I suggested that one
of the reasons for keeping the LC syntax was that it
could be faster than list(genexp). Has anyone investigated
whether any speed is being lost by making them equivalent?
