Re: function.hpp: the word Functor

It seems that function.hpp contains a word 'Functor',
use to describe a class emulating a function.

The best word to use is Functoid (or even Function!!). 
The entity described is NOT a functor. 
That word has a precise technical meaning in mathematics: 
a functor is a structure preserving map.
The terminology is used extensively in computer science literature,
and is even a keyword in SML (where the use really is intended
to provide a model of a functor).
