Bug Description
Hi,
I frequently want something similar to MatchesAll, but where it applies one
Matcher to an iterable of matchees, collecting all the mismatches (or perhaps
with an option to just return the first as it is hit.)
Shortly after writing a Matcher I will find that I want to test a list of things to
check that they all match, so having a generalised way of doing that would
be great.
results = [x for x in map(matcher.match, matchees) if x is not None]
if results:
return MismatchesAll(
Thanks,
James
