Context managers are smart..er than you think...

context_test.py

class mycontext(object):
    def __enter__(self, *args, **kwargs):
        print 'enter'
    def __exit__(self, *args, **kwargs):
        print 'exit'


def myfunc():
    with mycontext():
        # Gee what will happen here?
        return 'Returning'

def main():
    print myfunc()


if __name__ == '__main__':
    main()
