With statement should allow suppressing exceptions

[Patience Shyu]

class BlockExceptions(object):
    def __enter__(self):
        pass
    def __exit__(self, *args):
        return True

with BlockExceptions():
    raise ValueError()

The ValueError should be suppressed according to https://docs.python.org/3/reference/compound_stmts.html#with. Currently the exception is not suppressed, it fails with
