Better usability of stash refs

To drop a stash, I have to do this (example):

$ git stash drop stash@{3}

Using the full "stash@{N}" seems superfluous since the documentation states it must be a stash in the first place. It would make more sense (and be quicker to type) to do:

$ git stash drop 3

Is there a trick I can use to make this shorthand possible? I thought about creating a "s" script for "stash" that intercepted the parameters for only a couple of stash sub-commands and created the ref, but that seems a lot of work.

Any productivity tips here? Thanks in advance.
