Re: [Haskell-cafe] How to write Source for TChan working with LC.take?

20 May 2012

      Oops, sorry.
The last case's behaviour was not as I expected... A correct log is below:

~~~~
ghci> sourceTChanRaw ch $$ LC.isolate 10 =$= LC.mapM_ print
()
()
()
()
()
()
()
()
()
()
ghci> sourceTChanState ch $$ LC.isolate 10 =$= LC.mapM_ print
()
()
()
()
()
()
()
()
()
()
ghci> sourceTChanYield ch $$ LC.isolate 10 =$= LC.mapM_ print
()
()
()
()
()
()
()
()
()
()
*blocks*
~~~~

So again, sourceTChanYield blocks here even if it is already supplied with enough values!
