Return true if the specified lhs compares equal to the specified rhs using the equality-comparison operator, lhs == rhs. Implemented inline because of all the duplication of std::forward<TYPE1>(lhs) == std::forward<TYPE2>(rhs).

decltype(std::forward<TYPE1>(lhs) == std::forward<TYPE2>(rhs))
operator()(
TYPE1&& lhs,
TYPE2&& rhs) const noexcept(/* see-below */);
This function is potentially-throwing unless noexcept(std::forward<TYPE1>(lhs) == std::forward<TYPE2>(rhs)).
The return value should not be discarded.
