Comment:
I'm afraid I don't understand this feature. Could you write a Wiki page
that gives the specification? A single example isn't enough to say
* what the syntax is
* when it typechecks
* how it desugars
Maybe I'm wrong, but it has the smell of being closely related to the work
of George and friends on monad comprehensions; see
[wiki:MonadComprehensions]. In paricular their as-yet-unimplemented
proposal to overload list literals; Section 5.2 of their paper
[[http://db.inf.uni-tuebingen.de/files/giorgidze/haskell2011.pdf "Bringing
back monad comprehensions"]] at the 2011 Haskell Symposium. I'm adding
George and Jeroen in cc.
