What's the practical reason of having a macro?

The approaches suggested in the thread all have limitations. For example
they require you to put some unique non-ambiguous type in all your
overloads of a said function.

The classical approach recommended for enable_if is still the best way
to use SFINAE for a boolean meta-function or a boolean constant expression.

For this one, you're better off just knowing what you're doing than to
rely on macro magic.
