0.10.5, 6.10.1 btw.

Digging around with the commented query -- that a "pure (string)" is getting delayed -- I've hit a rather fundamental problem: it seems Event doesn't obey the Monad laws. I don't know whether this is a known issue or whether I'm being plain stupid, but this:--
module Main where
import FRP.Reactive import FRP.Reactive.LegacyAdapters import Control.Concurrent import Control.Applicative import Control.Monad import Data.Monoid import Data.Maybe
main = do clock <- makeClock (sink, evnt) <- makeEvent clock forkIO . sequence_ $ repeat (getLine >>= sink) adaptE . fmap putStrLn $ (pure "A Line!" `mappend` evnt) -- adaptE . fmap putStrLn $ (pure "A Line!" `mappend` (evnt >>= return))
and the same with the penultimate line commented instead of the last, appear to have different behaviours: in the version shown, "A Line!" is printed when the program starts; and in the other, this is delayed until after the first line is read (but before it is printed).
Should this happen?

Hi
As part of studying the Reactive library, I have created a simple game. The object of the game is to guess a number.
As I am a newbie with respect to FRP, I assume that my game could have been implemented more elegantly. Comments are most welcome.
The game can be found here http://hpaste.org/fastcgi/hpaste.fcgi/view?id=3037#a3037 and it is attached.
Greetings,
Mads Lindstrøm
