[Python-Dev] Wishlist: dowhile

More than case-statement semantics or PEP343, I wish for a dowhile

The most straight-forward way is to put the conditional expression at
the beginning of the block with the understanding that a dowhile keyword
will evaluate the condition only after the block runs:

    dowhile <cond>:

being the equivalent of;

    _firstpass = True
    while _firstpass or <cond>:
        _firstpass = False
