Re: [Haskell-cafe] does try force evaluation of IO value

if i have some lazy io action, assuming (maction :: IO a) which may raise exceptions while running, will "try" force evaluation of "a" to determine is exception raised or not ? Sorry for my broken english.

No, it won't force the return value. To do that, use evaluate http://hackage.haskell.org/packages/archive/base/latest/doc/html/Control-Exc... Roman
