New submission from Michael Grazebrook <michael at grazebrook.com>:

This code fragment from the documentation of iter() doesn't work as intended. Change "STOP" to "STOP\n". Maybe also check for EOF as it hangs.

with open("mydata.txt") as fp:
    for line in iter(fp.readline, "STOP"):

Or maybe this makes a better example because it's clearer wha'ts going on:

square_generator = (i * i for i in range(100000))
for n in iter( square_generator.next, 144):
    print n
