Comment (by simonpj):
Conal,
Your comments say that the test program imports `Interface.TV`. But it
doesn't; the test program you give imports `Interface.TV.UI`, and that
module does not import Interface.TV.OFun.
So I'm not surprised at the behaviour you are seeing. Are you? GHC
"sees" the instances in the transitive closure of the module import graph.
I'd try variations, only that means I have to install DeepArrow etc, which
I could do, but haven't yet.
Puzzled
Simon
