[Haskell-cafe] Code review request - using ErrorT

Dear gentle Haskellers, I'd appreciate it very much if you could please take a look the my code here and give me some feedback - https://github.com/ckkashyap/haskell-websocket/blob/master/src/lib/Net/WebSo... I am particularly looking for advice around what would be a good type for a server handler function that does IO and needs to short circuit if it fails at any point also needs to thread a state along. I am considering this - ErrorT String (StateT Int IO) Data Regards, Kashyap
