Hi,
Good question. I'd like to know the answer too.
Cheers,
Alex.

Hi everyone,
Dumb question about declaring a function and type synonyms.
There are to different declarations of the same function:
attrNames :: String - AttrDict - [String]
attrNames :: AttrClass - AttrDict - AttrNames
First gives you the idea about exact types it expects (except AttrDict for

Hi guys,
Do we have anything like half precision floats in Haskell? Maybe in some non
standard libraries? Or I have to use FFI + OpenEXR library to achieve this?

Okay looks like FFI is the only way to go, Thanks.

Yes, I mean sizeOf 2. It's useful not only on GPUs but also in normal
software. Think of huge data sets in computer graphics
Awesome!

Hey guys,
It's a dumb question but I'd like to know a right answer...
Let's say we have some geometry data that can be Sphere, Cylinder, Circle
and so on. We can implement it as new data type plus a bunch of functions
that work on this data:
data Geometry = Sphere Position Radius

this:
perimeter :: Geometry - Double
perimeter (Sphere _ r) = 0.0
perimeter (Circle _ r) = 2.0 * pi * r
The latter is even simpler because there is no need in extraction of Double
value from Maybe.
So the question is still there: do I need a type class?

Cool. It's more and more clear guys.
Thanks a lot. I'll check that expression problem.
Existential types sounds a bit scary :)

It's unfortunate that they've developed a scariness feeling associated with
them. They can be used in strange ways, but simple uses are quite

You can't reuse the same operator in different classes. Vector owns
(^+^), so Matrix can't use it itself. You could

Yeah guys. I confused myself. I forgot why I had to implement several +
operators (^+^, ^+, ^+. etc.) for Vector class. Now I've got an idea again.
Different names make a perfect sense.
Thanks a lot.

It's probably a simple question but I can't find a proper solution...
Suppose we have a class Vector which overloads (+) operation. I'd like to
represent a Matrix data type as a set of vectors:

In this case (+) for matrices could be

Hi guys,
Any ideas how to integrate Haskell into other software as scripting engine?
Similarly to Python in Blender or GIMP or to JavaScript in the products from
Adobe. Which possibilities we have?
