Indeed. The original poster seems to want something that would work (not
necessarily look) like this:
do:
<block>
while <condition>
with <block> executed once prior to <condition> first being tested. But the
above is ugly, and you can get much the same effect with Python today:
firsttime = True
while firsttime or <condition>:
<block>
firsttime = False
Seems fairly Pythonic to me. YMMV.
