bind2nd/bind1st is used like a cvctor


find_if ( &array[0], &array[2],
bind2nd(greater< int>(), 55)


If you have trouble making out the objects in such a call to bind2nd,
here's a simple rule

bind2nd always takes objects and instantiate another object, not a type

It's like a converter constructor, but bind2nd is actually a function template.

In our example,

* greater< int>() is an Object, not a type, not a function
* find_if needs an Object (not a type) as argument
