Implement generalised list comprehensions
This patch implements generalised list comprehensions, as described in
the paper "Comprehensive comprehensions" (Peyton Jones & Wadler, Haskell
Workshop 2007). If you don't use the new comprehensions, nothing
should change.
The syntax is not exactly as in the paper; see the user manual entry
for details.
You need an accompanying patch to the base library for this stuff
to work.
The patch is the work of Max Bolingbroke [batterseapower@hotmail.com],
with some advice from Simon PJ.
