If someone came with a nice syntax I’d be for this. I can’t imagine what that
would be.
I doubt there is an alternate prefix or postfix operator that would pass
muster, due to ‘!’ already meaning the appropriate thing in so many languages,
and swift only supporting symbolic operators.
I can’t think of a method on boolean which would read properly either, e.g.
if isValid.not() {…}
The closest I could think to a decent bike shed color would be a global
function:
if not(isValid) {…}
