PEP-315 ("do" loop)

[Andrew Koenig]

> Most other languages have a way to put the test at the bottom of the loop.

>        line = sys.stdin.readline()
>     until: line == '\n'

I believe it would be more useful to allow the test to be anywhere in the
loop, not just at the beginning or at the end.  Even better would be to
allow more than one test.
