Implementation of invoke_result<t_FN, t_ARGTYPES...>. This specialization is instantiated in C++11 and later when t_FN is neither a pointer‐to‐function, pointer‐to‐member‐function, nor pointer‐to‐member‐object type, and the INVOKE(fn, args...) expression is well‐formed given fn is an object of the specified t_FN type and args... are objects of the specified t_ARGTYPES... types. The INVOKE(fn, args...) expression in this case is fn(args...).

type

For C++11 and later, the type of the INVOKE(fn, args...) expression given fn is an object of the specified t_FN type and args... are objects of the specified t_ARGTYPES... types. The INVOKE(fn, args...) expression in this case is fn(args...).

myDeclval

Return a reference to the specified t_SOME_TYPE template parameter type; if t_SOME_TYPE is an rvalue, then the returned reference is an rvalue reference. This function is declared but not defined and is intended to be called in an unevaluated context. Because there is no definition, the available constructors for t_SOME_TYPE are irrelevant.
