#2465: View + Pattern Match not fused sufficiently

---------------------------------------------+------------------------------
This came up while playing with the ICFP2007 task.
I have a function {{{dnaView :: DNA -> [D]}}}; DNA is a {{{[ByteString]}}}
and D is just the enum {{{I|C|F|P}}}. When I call a function that just
pattern matches on the result, I think the pattern matching function
should be fused with the view -- the view should run as a coroutine.
I've attached an example.
