OK. Unfortunately it is not possible to get GHC to recognize code in
that format without some preprocessing.

Sounds like the real issue is that you need better editor support.
What editor are you using? I am just curious, I am not going to
suggest that you change editors. =)

I'm using Sublime Text. I do like it a lot! I disagree that what I need
is a better editor. What is the more popular to annotate code today:
Github Markdown or Latex? The source file of a latex document is not
amenable to be read as you are coding, but Markdown is. So, it helps
make the code cleaner. ;-)

I didn't say you need a better editor! I said you need better
*support* from your editor for writing literate Haskell code. I don't
know much about Sublime Text but you might find this useful:
https://bitbucket.org/wrossmck/literate-haskell-bird-style
Anyway, I agree Markdown is better for annotating your code, unless
you are writing a paper about it.

This is about syntax of Haskell.
I am reading the source code of Yampa. I find that a definition like the
following
data SF' a b where
SFArr :: !(DTime -> a -> Transition a b) -> !(FunDesc a b) -> SF' a b
in Yampa.hs.
