Yeah. It doesn't. It doesn't even behave the same wrt erroneously typed
arguments
I understand the care taken, but the spec gives reasons to believe
otherwise:
There is opAdd and opAddAssign
There are opEquals and opIn, but no opNotEquals and opNotIn.
If you can override the operators independently, naturally you should not
expect that one is rewritten, otherwise why have the independent operators?
Likewise, if there is no overload for the opposite, then it must be a
rewriting function.
'is' is sorta different because you can't override it either way.
