Most SFINAE constraints in the library are specified via:

Shall not participate in overload resolution unless [positive condition]

There is a small minority that use:

Shall not participate in overload resolution if [negative condition]

In other words, most are phrased as a condition for "enable if" but some are phrased as a condition for "disable if". It would be better to be consistent.

I think the "unless positive condition" reads better, unless we get an actual English negative in the "positive condition".

LWG is working on a new element to convey this information replacing these magic words: P0788.
