How about adding a month_length method similar to is_leap_year? I peeked in the source to see one CAN do this:
DateTime->_month_length($dt->year, $dt->month)
to get the length of the month of a DateTime object but
this is ugly and the _month_length method is supposed to be 'private'.
Given the bountiful plethora of accessors I would have expected
this to be present as well.
