In some cases you do want it to be aware of the promise if you chain
many async operations together, and only fulfill promise at the end of
the chain. However a simpler interface for the one-async-operation case
would be nice, I agree.

Hmm, I think I'd prefer a non-member function to make the distinction
between that act of settingthe promise and the act of composing another
function object clearer when reading the code. I don't see any
implementation reason to make it a member function - is there one?
