*
* Metafunction:
* A metafunction is a class or a class template that represents a function invocable at compile-time.
* An non-nullary metafunction is invoked by instantiating the class template with particular template
* parameters (metafunction arguments). The result of the metafunction application is accessible
* through the instantiation's nested type typedef.
* All metafunction's arguments must be types (i.e. only type template parameters are allowed).
* A metafunction can have a variable number of parameters.
* A nullary metafunction is represented as a (template) class with a nested type typename member.
*
* Metafunction Class:
* A metafunction class is a certain form of metafunction representation that enables higher-order
* metaprogramming. More precisely, it's a class with a publicly-accessible nested Metafunction called
* apply. Correspondingly, a metafunction class invocation is defined as invocation of its nested apply
