```
```[1] Note the implication of this: a function pointer *T (*f)(X,Y)* is a Binary Function, but not an Adaptable Binary Function: the expressions *f::first_argument_type*, *f::second_argument_type*, and *f::result_type* are nonsensical.

[2] When you define a class that is a model of Adaptable Binary Function, you must provide these *typedef*s. The easiest way to do this is to derive the class from the base class *binary_function*. This is an empty class, with no member functions or member variables; the only reason it exists is to make defining Adaptable Binary Functions more convenient. *Binary_function* is very similar to the base classes used by the iterator tag functions.
