It’s not you who has to wait, it’s US!
One of the things that intrigues me about Haskell is marrying functional programming to Haiku’s excellent threading and multi-core support. It has been said that one of the most difficult aspects of programming for Haiku is dealing with thread synchronization issues: race conditions, semaphores, variables in correct scope, deadlocks, etc. Haskell shows promise is addressing those difficulties, at least in theory.
But I guess we will have to wait until R1 to try it out…
