Too short. Having such a short identifier does two things:
* Robs that identifier from any future possible use
* Creates incentive to use this over "my"
You want there to be a general tendency to use "my" first. If I were to
choose a word, it would be "temp" (which I think already exists, though
I forget what it does vs "my"), or "let" (to correspond with its use in
rules).

The reason I didn't want a new type to be valid was as an extra
precaution against problematic boilerplating. It's a minor thing, and
probably not that big a deal.
