No, my good man... I did not forget <wink>. readlines()
would require me to download the whole thing in one
go, and that isn't necessarily what I want.
The point was whether or not they should be iterable,
like normal files. I mean, it is fully possible to
for line in open('foo.txt'):
(Just check out 2.2 or the iterator PEP.)
This is, however, not possible with the semi-file-like
objects of urllib. I guess this is simply a matter of
lag, but you never know...
