RFE: Allow assertions on multiple objects to behave as one.

Something like:

def assert_all(*assertions):
    assertion_failed = False
    assertion_message = []

    for (actual, matcher) in assertions:
        try:
            hamcrest.assert_that(actual, matcher)
        except AssertionError as e:
            assertion_failed = True

            assertion_message.append(e.message)

    if assertion_failed:
        raise AssertionError(''.join(assertion_message))

would be great. It performs all assertions before failing so it can report on 
all violations. It also allows verifying different objects (eg ensure different 
files have different characteristics) and keeps the SUT and its matchers paired 
for better readability.
