struct InvokeResult_FunctorImp<bslmf::VoidType<decltype(InvokeResult_ImpUtils::myDeclval<t_FN>()(

: /* implementation-defined */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...).
