[Haskell-cafe] How can I stop GHCi from calling "show" for IO actions?

Prelude> let inf = repeat 1 Prelude> inf [1,1,(lots of output until I press ctrl-c),Interrupted. (I expect this to happen) Prelude> let x = inf (no output here!) Prelude> :t x x :: [Integer] Prelude> return inf [1,1,(lots of output until I press ctrl-c),Interrupted. (I also expect this to happen) Prelude> y <- return inf [1,1,(lots of output until I press ctrl-c),Interrupted. (I do not expect this to happen here!) Prelude> :t y <interactive>:1:0: Not in scope: 'y' Is this a bug? Why does "y <- return exp" have different behavior than "let y = exp"? Is there a way to make GHCi not print the result of an action but still make my variables get bound? -- ryan
