Is "break if" legal in loops that have their own conditions as well,
or only in a bare "while:" loop? For instance, is this valid?
while not found_the_thing_we_want:
data = sock.read()
break if not data
process(data)
Or this, which uses the condition purely as a descriptor:
while "moar socket data":
data = sock.read()
break if not data
process(data)
Also - shouldn't this be being discussed first on python-ideas?
