Actually, my plan for aliases was to leverage environment variable
substitution, so

aba get --link !tom
is converted to
--link $tom
which then turns into
--link address@hidden/tla--devo--1.2

So there needs to be a leading character, though ! is pretty well an
arbitrary choice.

Also, I was intending to allow alias expansion for any argument, not
just package/version names.

I think you mean "linux-2.16ac--patch-42".

But this is possible without new rules too:
get !linux2.16ac--patch-42

One issue where I think we see differently is that I envisioned aliases
as a per-user setting, and this discussion seems to be about a
distributed form of aliasing.

Distributed aliasing makes it even more important for the user to
request alias expansion, since packages may add aliases that conflict
with the names of other packages.

I should have something that does my form of aliasing in the next week,
but if anyone wants to give me a patch, I'll gratefully accept it.
