If someone could write a sentence or two to explain why gcd 0 0 = 0,
(ideally, brief ones I can put in the report by way of explanation),
I think that might help those of us who have not followed the details
of the discussion.
Here it

To make clear why $0$ (and not any other non-zero integer) is the

I am pleased to announce an experimental release of GCJNI.
GCJNI is a library that allows Haskell to invoke Java code via the
Java Native Interface (JNI). The implementation uses GreenCard to make
the JNI (a C language interface) available to Haskell. GCJNI includes
a few convenient features,
I am pleased to announce an experimental release of Haven,
a library for scalable vector graphics in Haskell.
Haven provides a wealth of features, including:
- Data types for common geometric shapes such as rectangles,
ellipses and Bezier curves.
- Composition of arbitrary shapes from

Eh, you beat me to a first release, which I was going to announce
yesterday, but SourceForge's file release system is currently broken. I
guess I'll have to put it on semantic.org

Hi Ashley,
I'm not quite sure why you Cc'ed the whole Haskell list in replying to my
release announcement, but just for clarification:

I find it odd you would say that. When you first mentioned your interest in the
JNI
I'm not a compiler/interpreter implementer, just a
Haskell user :-)
My question is: if I have two datatypes,
say
newtype Attributes = Att [String]
data Instance = Instance Attributes
[Int]
where an Attributes value describes the discrete
attributes that are stored (as Int) in an Instance.
HsParser miscalculates column-positions if qualified names are used.
The problem seems to be the lexer forgetting to count the '.' in the
qualified name when deciding how much to move forward. In this
function, for instance,
f M.A M.B M.C = 0

Hi guys,
With the module
