<div name="messageBodySection">Hello,<br>
I'm trying to use Data.Conduit, but I get stuck with mapAccum as how to get and retrieve the result.<br>
If I use it, I get a simple conduit like :<br>
<br>
testC :: ConduitM () Int IO Int<br>
testC = Src =$= cdt where<br>
src = CL.sourceList [1..10]<br>
cdt = CL.mapAccum (\x s -> (x+s, x) 0<br>
<br>
I can get the output with<br>
testC $$ CL.consume<br>
but how do I retrieve the accumulated sum ?<br>
