I'm trying to test some gtk2hs gui code without compiling it first, just

Gtk2hs then complains about running in a multithreaded ghc, ie. one with

Hi Dan!
You might want to change the following:
shuffleRec :: StdGen - [a] - [a]
shuffleRec g list = x:shuffleArr g' xs
where
(n,g') = randomR (0,length list-1) g
(x:xs') = drop n list
xs = take n list ++ xs'
into the following:
shuffleRec :: StdGen - [a] - [a]
shuffleRec g list

That doesn't explain the quadratic behaviour of shuffleArr, though.
I suspect it's laziness, things aren't actually done until the result is
finally demanded, but I would have to take a closer look to really find
out.
Yep.

No, but you can unsafeInitGUIForThreadedRTS.

in that Div alternative I should create expression
