Creating an alias for a branch: is it possible?

[Arcady Genkin]

I've branched a stable branch off a source tree, named rel-1-0.  I
wonder if I could have a branch "alias", for example, `STABLE', that
would always point to the latest stable branch.  For example, when in
the future rel-2-0 will be branched off, I want to just move `STABLE'
alias to point to rel-2-0 instead of rel-1-0.

The idea is that the users would track `STABLE' sticky tag instead of
a particular release for bug fixing in current stable branch.

Is this doable?  Is this a good idea at all?

Many thanks,
