Okay, going way off on a tangent here, but I don't think the Perl
interpretation is quite as obviously correct as you think it is;
there's

There certainly is the unary minus even though it is badly interpreted in some
languages, thank

Sure. But that's different from saying "Ok, you can only define an /
