Agreed with nick's idea, the implicitly recreation of the context managers
would confuse users.
How about removing the "generator must yield exactly one value" restriction of
@contextlib.contextmanage? Then if I want a generator to be used as a common
context manager, I can make it yield exactly one value, else further if I want
the resulting context manager can be used as a decorator, (reusable), I can put
the generator code in a "while True" loop and add a "yield" at the end of loop
body, like this:
@contextmanager
def func():
while True:
print('begin func')
yield
print('end func')
yield
:)
