There is one example (just before section II) in the proposal, but because 
Bind and Function are completely separate libraries (with separate 
proposals), the proposal does not expand on the example.

There is an example of using the two libraries together here:
  http://www.boost.org/libs/bind/bind.html#with_boost_function
but perhaps we need something that says "if you want to store a bind object, 
use Function" instead of "if you want to use Function with bind, you can do 
this (storing a bind object)".
