Comment (by anonymous):

 The documentation does indicate a function object "F f", but the
 implementation (in 1.53) takes "F const&". So if no copy of the function
 object is made (and I can't see why it should), it seems:
 1. The documentation should be corrected.
 2. Given that no copy is necessary, why not accept a non-const "F& f"
 argument?
