Whatever keyword is chosen, I hope PEP 310 eventually hit Python, I have been
awaiting it for a long time. I would also like to have a builtin resource()
like this:
def resource(enter_call, exit_call):
class Res(object):
__enter__ = lambda self: enter_call()
__exit__ = lambda self: exit_call()
return Res()
with resource(self.mutex.lock, self.mutex.unlock):
pass
Either that, or "with" could call adapt() implicitly so I can register my
conversion functions.
