There is a declval function on Boost.Utility that creates a rvalue reference that could be used instead of the make() function. Please could you check if this function is adapted to your needs?
Unfortunately I need a l-value, espacially for += type of operators.
declval should give you an lvalue if you give it a (lvalue-) reference type, e.g., declval< T& >() where T is a non-reference type... [...]
Last I agree that the use of equal should be replaced by assign when assignment is intended += has_operator_plus_equal -> has_operator_plus_assign -= has_operator_minus_equal -> has_operator_minus_assign
Why? is it to avoid confusion with "equal to"? I like plus_equal because plus is a sign and equal is also a sign. So I think it is easier to remember.
I prefer op_equal as well, but it's not a strong preference. - Jeff
