well for the extension functions I wrote that if the ref parameter is the first argument and it's called with ufcs syntax, it could implicitly add the ref probably.

Surely better than just requiring ref everywhere. But still, a.swap(b) just feels intuitive. Hard to say what I like here, because the ref parameter is usually the first anyway. Besides swap() you rarely use more than one ref parameter.
