E.g., so we could write
for x in seq if x is not None:
print repr(x), "isn't None ;-)"
instead of
for x in (x for x in seq if x is not None):
print repr(x), "isn't None ;-)"
just a thought.

Thank you guys! (Reinhold, Mark and Markus) I must confess that I am
absolutely awe struck at the power of this language! There is no way in the

It really does depend. For instance, some other programmers where I
work came up with a way to represent a hierarchical, somewhat random
data set by creating each object and then adding attributes to those
for each subobject, and so on down the tree. However, you could never
