Will be good to see people again! Looking forward to it.

It's a GHC problem? it's normal than signature is order-dependent?
I think this is on purpose. The error specifically says that the

Hello!
I'm happy to announce the first release of HoleyMonoid, a datatype that
helps you build monoids with holes in them. The holes are filled in
later using normal function application. For example:

Dear Haskell Hackers,
Many thanks to all those who attended Hac5! We had a spectacular number

countries. Many thanks also to the organising committee and sponsors!
Those bagels on Sunday were delicious. :-)

30 of my 1014 test cases do so.
1014 test cases?! Wow. :-)

Bonsoir café,
It is my pleasure to announce version 0.4 of Yogurt, a functional MUD
client. Version 0.4 makes Yogurt available as a standalone executable
that is able to dynamically load and reload Yogurt scripts. Here is a

This will be a big help in my MUD driver. Thanks! :-)

Dear Haskellers,
I'm pleased to announce the release of Yogurt-0.3!
This version improves over 0.2 in several ways:
* It compiles and runs with GHC 6.10.
* The Mud monad is now built on top of IO.
* Vars are expressed as IORefs. No more unsafeCoerce needed.
* Forking of threads is supported, wi

I've defined a function `count` that returns a function with

Take a look at the isBottom function which is defined in module
