Hmm, this will make it rather complex for my students since they have not much
experience with Haskell programming. In addition, where can I find
documentation about Graphics.Rendering.OpenGL.GL.VertexArrays?

Too complicated for the practical course. Doesn't OpenGL already do something

Maybe also too complicated or too extensive for the practical course.

I did not refer to the overheads of the binding but to "the slowness of
Haskell" (compared to C, of course ;-) ).

Is there one for Haskell?
