Hi, You're looking for 'when' as in:

do condition <- something when condition $ other things more things

http://hackage.haskell.org/packages/archive/base/latest/doc/html/Control-Mon... It is quite handy. Take care, Antoine On Wed, Dec 29, 2010 at 10:14 PM, Magicloud Magiclouds wrote:

Hi,  In Haskell's way, normally, we write: if condition then  expression_true else  expression_false

 But I just heard that, in fancy way, we could do: do  ifNeedToDo >> doIt  bluh

 May I have any clue here? -- 竹密岂妨流水过 山高哪阻野云飞
