Syntax
bool __is_function( typename T )
Returns true if and only if T is a function type.
Returns false for reference/pointer to function type.
Returns true for specialization of a function template.
Ill-formed if called with the name of a template, without specifying the template parameters. A template is not a type; it is a type generator.
