or  maybe a formal BoF? after all, how formal do they get?

Anyway, it was my understanding that we really needed to do some significant refactoring of how numpy deals with dtypes in order to do this kind of thing cleanly -- so where has that gone since last year? 

Maybe this conversation should be about how to build a more flexible dtype system generally, rather than specifically about unit support. (though unit support is a great use-case to focus on)
