I have on occassion used lambda as a poor-man's let, but only if I needed to
avoid multiple evaluation:

 res = (lambda x=blah(...), y=blahz(...):  f(x*y,x+y))()

I'm sure most people would debate it's more readable, but it's IMO superior to
cleaning up manually with ``del``. I sometimes also find it useful to avoid
cluttering up the interactive shell.
