Re: [Haskell-cafe] [C Binding] Turning the mutable to immutable?

I think it might influence performance, but it doesn't have to be that much. There are some optimization tricks you can apply to deal with this. Premature optimization is the root of all evil ;) -chris On 7 jul 2010, at 11:40, Yves Parès wrote:

That's indeed an advice I've read [1]. But wouldn't it damage the performances, since code will have to go through an extra layer?

Hello,

I don't know if some of you are familiar with the SFML library (stands for Simple and Fast Multimedia Library) --> http://sfml-dev.org As SDL, SFML is a 2D graphics library, but conversely to SDL it provides a hardware-accelerated drawing, through OpenGL. Well, I'm currently writing its Haskell binding, and I'm stuck with design issues. What I'm heading to is a full IO binding, and that's what I'd like to avoid.

Have you considered writing a low-level binding and building a high-level library on top of that?
