- When two or more different declarations are specified for a single name
4
- in the same scope, that name is said to be *overloaded*, and the
5
- declarations are called *overloaded declarations*. Only function and
6
- function template declarations can be overloaded; variable and type
7
- declarations cannot be overloaded.

- When a function name is used in a call, which function declaration is
10
- being referenced and the validity of the call are determined by
11
- comparing the types of the arguments at the point of use with the types
12
- of the parameters in the declarations that are visible at the point of
13
- use. This function selection process is called *overload resolution* and
14
- is defined in  [[over.match]].
