[boost] Concept for function object with result_type?

I know we have AdaptableUnaryFunction, which covers function objects
with nested result_type and argument_type.  But we've long since
learned that argument_type is really unnecessary, and plenty of
libraries are looking at result_type alone (e.g. bind).  Do we have a
concept for that sort of function object?  If not, what shall we call
it?

Should we rather invent a concept for "UnaryFunction that works with
boost/tr1::result_of<>" ?  Maybe DeducibleUnaryFunction?
