weakattrs are data descriptors, just like properties etc. they are part
of the class, not the instance, so there shouldn't be any trouble with
mixing those with __slots__

moreover, adding those to stdlib is very staight-forward. we don't even
need to introduce a new module. if people show interest, i'll write a
bit of a longer doc string and add some unit tests (although there's
not much to test :) )
