Out the corner of my eye I'm watching the DateTime development. I noticed a nit: in code like lib/DateTime.pm there are constants like 1_721_424. I don't know what that means, but it would be nice to let Perl's constant-folding take care of this so the source code could be clearer about a purpose:
% perl -MO=Deparse -e 'print 4*5*6*7*8*9' print 60480; -e syntax OK
So you can just write 1_721_424 as whatever mathematical expression it comes from, which I think is maybe (393 * 365 + 7) * 12 ?
