Works for me, though I wouldn't cry if the "while" was changed to
"until" to make the difference between this form and the "while" loop
more obvious. I don't think there's a good argument for _both_
do-while and do-until, but one or the other would be useful.
The biggest objection I see is the addition of one or two more
keywords, but I don't recall using "do" or "until" as a name in any of
my programs...

Syntax is the problem? Specifically the position of the condition
after the loop body? How do you explain the syntax of the new Python
ternary operation, with the test in the middle, even though it
logically has to be done first?
Right now, I tend to write these loops something like
while 1:
do_stuff()
if exit_condition: break
which offends my sense of aesthetics, but it works.
