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

2010/7/7 Liam O'Connor Making an immutable API from a mutable one generally damages performance (on von neumann architectures) somewhat, the goal is to minimize that impact.

In fact, I would like to determine if an EFFICIENT way to make images and such immutable exists, or if it is impossible. I looked at graphics-drawingcombinators. It is nice, but it doesn't fully answer to my problem since it just loads images and draws them. It provides no ways to alter them, no problem of mutability, then.

Yes, you are right, this is wise.
