Comment (by guest):

 (WikiFormatting fixes)

 GHCi can do some weird things, with the letter g and the up arrow:

  > ghci
  ghci> :m Control.Concurrent
  ghci> threadDelay 5000000
  (now, while thread delay is running, press the up arrow once)
  (once the computation has returned, the following will be on the line)
  (i.e. you don't type threadDelay again)
  ghci> threadDelay 5000000
  (now just press enter)

 <interactive>:1:0: Not in scope: `ghreadDelay'

 This works for any computation that runs long enough for the user to press
 up while its still going. The result is always a g replacing the first
 letter - I have had gain for main etc. And the buffer always appears
 correct to visual inspection.
