Re: [Joda-interest] Partials

Sounds interesting!

I think that we will still want some concrete (immutable) implementations of
the rounding though? It doesn't feel quite right creating a 'DateTime' and
then only using the date parts.

I maybe wrong though, can't tell until I see how the API works out from this
idea. Can probably wait until after you check in the basic support for final
decisions on this.

BTW, Partial YearMonthDay now checked in. DayOfWeek is just seven constants,
so it needs to be coded differently ;-)
