Hi,
1. Minor correction for your tutorial: reverse . reverse = id is
called the involution property, not idempotency.
2. Writing haddock documentation would definitely increase the chances
for GenCheck wide adoption.

Can you provide me a quick

packages. The new package does everything they can do, but better.

Indeed, thank you. mtl is cruel with me for
the second time uumpf. But it's strange mtl
just reexports transformer's module

Maybe I export State from one library version
and instance from another?

I'm reading Conal Elliot's paper, Push-Pull FRP. At some point he needs an
unambiguous choice operator, essentially to implement select: a future that
waits for one of its future arguments to fire. His implementation of unamb
creates two threads racing on a shared MVar. By his own admission, this

I've been trying to send mail to the cvs-ghc mailng list and the list

a) Made sure I was sending mail with the subscribed from address.
b) Unsubscribed and re-subscribed and tried again.
All to no avail. Is there a moderation queue on
Cafe,
I was watching a panel on languages[0] recently and Martin Odersky (the
creator of Scala) said something about Monads:
What's wrong with Monads is that if you go into a Monad you have to change
