I am sorry to say, I do not like it very much. It makes a lot of code to add
and maintain for the sole practical result of abbreviating "concat=a=1:v=0":
that is not a very good investment.

As for the frobnicate/afrobnicate symmetry, I see the afrobnicate variants
as a constraint caused by the current design (type can not be negotiated or
guessed): if someone comes with a smart idea on how to eliminate them
without too much code, I would deprecate the afrobnicate variants in a
heartbeat. And in particular, I would suggest to deprecate amovie right now.

Note that we will actually need a solution to the type problem before we
start randomly implementing dsplit or ssetpts.
