[Haskell-cafe] Asking for advice on category for a paper for ICFP

Hi! I'm trying to write a paper for ICFP, This is my first paper of this kind. Can you please help me to choose the right category for it? The paper is about a novel technique of implementation of FRP. I've studied the Haskell FRP zoo and I can confirm that it's novel. In my opinion it's very elegant and simple, but of course I'm biased :) So far so good. Can you please help me to choose the right category for it? Is it a normal research paper or is it a functional pearl? So the FRP is an old technique, but I propose a novel variant of implementation which I hope is easy to study even in normal class rooms and does not contain unsafePerform tricks. Cheers, Anton
