PEP 340 describes the block statement translation as:
itr = EXPR1
val = arg = None
ret = False
while True:
try:
VAR1 = next(itr, arg)
except StopIteration:
if ret:
return val
if val is not None:
raise val
break
try:
val = arg = None
ret = False
BLOCK1
except Exception, val:
arg = StopIteration()
It uses a variable "ret" that is always False. If it does manage to take on
a True value, a return statement is executed. How does ret become True?
What's meaning of return in this context? Something seems amiss.
