My impression from having tried it briefly is that it's not great at real-time stuff because of its lazy evaluation. Do you find that to be true, or is that not an issue in real life?
Lazy evaluation does make understanding performance/memory behavior hard, but usually you'll be using pipes/conduit/machines instead of lazy lists in production code, so its not much of an obstacle for real-time behavior.
However GHC's garbage collector can be an issue for real-time code, having high 99th percentile latencies.
