Yes. That is exactly what stash is for. Temporary fixes. Now...

That's the idea. You could take a snapshot automatically every x
minutes. For example: I'm testing it taking a snapshot on every
build/compile of my project (and it is going fine, BTW).

Except that, in this solution, you have only ONE saved state.
Also, it needs to be done manually. I wanted something automatic (like
John Wiegley's sugestion)

Making another analogy: I see stash like a stack (you push/stash, and
after you pop/apply). And I don't see stacks as a good long-term
storages <g> (ok, you CAN 'cheat' and see all items other than the
first)

Snapshots would be like a queue: You can keep it entirely, or you can
keep only the last 'n' interesting snapshots, removing the others.

I'm also not sure <g>. The idea of refs/ is a good one, too (and could
solve the problem of 'where to store the original index?'). But my
first idea of using branches was to avoid a load of another
'maintenance' commands ('snapshot list', 'snapshot delete', etc) and
to use a more known facility (branches).
