(This is in response to a discussion on #parrot.)
Rakudo (https://github.com/rakudo/rakudo/) uses tags of the form YYYY.MM for their monthly releases. When we were attempting to find the cause of a slowdown, somewhat was trying to find what commits occurred after the 2011.01 release with "git log --after=2011.01". His mistake was pointed out but this led to the confusion of why this was parsed as "May 1 2011" instead of "Jan 1 2011". Shouldn't date.c:match_multi_number() parse something with only two numbers as a beginning of month instead of allowing it to pass through to the generic parsing?
I'm currently nearing finals in school, so lack the time for an RFC patch at the moment.
