It's too easy to write your own reverse, however, the rest of these

I sort of like the ~ it's quick to type and not used elsewhere.
The other suggestions simply add obfuscation: pointer is misleading
and -1 is counter-intuitive.

Hmm. That's an interesting concept. It would certainly simplify
certain types of code.

Also interesting, and useful.
