We can have more consistent naming, at least.

I like this idea even more now, it means we could have a set of universal
operations:

$bool->negate(); // true -> false
$num->negate(); // 7 -> -7
$numericString->negate(); // "123" -> -123
$float->negate(); // 3.141592 -> -3.141592
$customVectorType->negate(); // (1, 0.5, -1) -> (-1, -0.5, 1)
//etc.

negate(); is just an example: that's usually done with an operator, I'm
really thinking more of things like sort() here. But you get the idea.
