I can also imagine some other scheme, where parse/format modules register
the formats they can handle with DateTime.pm.

But I'm very strongly opposed to something that just passes random strings
into new() and then loads the module on demand.

I guess that is the part that I don't understand. If you have the ability to add new parsing methodology to a list, you can just as easily subtract. So, if you want to use only the basic parsing and throw an error if you get a non-standard date format:

use DateTime ( parse => basic); # class-wide default
my $date1 = DateTime->new($dtstring); # better be ISO CCYYMMDD
my $sqldate = DateTime->new($sqlstr, parse => MySQL); # object override

etc.

This is a much more friendly interface for the average programmer.
