Subject Re: [collections] and what about 'identity'?

What's the use case for needing to vary the hash function? It's one of
those things where I assume there are incorrect ways to do it, and
correct ways, and among the correct ways fairly clear arguments about
which function will be better -- i.e. the object should provide the
best function.

I don't think subclassing or wrapping is a big deal in the rare case
you need this. But perhaps I am missing the use case.
