Maybe we should try to get the developers revive PEP 315.
This PEP whould introduce a do-while statement that looks
like the folowing:
do
statements
while condition
statements
this would be equivallent to:
while 1:
statements
if not condition:
break
statements
Those wanting something like:
repeat
statements
until condition
Could then write something like:
do
statements
while not condition
pass
Still not the most elegant but a vast improvement IMO.
