Traits for function pointers.
|

|

There are three types of functions: global, non-const member, and const
|
||||
member. These templates determine the type of function, which class type it
|
||||
belongs to if it is a class member, the const-ness if it is a member
|
||||
function, and the type information for the return value and argument list.
|
||||
|
||||
Expansions are provided for functions with up to 8 parameters. This can be
|
||||
manually extended, or expanded to an arbitrary amount using C++11 features.
