The arrow notation is closely tied to products. If you want to write an expression containing several variables, you need a tuple containing values for those variables (an environment). An asynchronous stream processor gives you a value for only one channel at a time. Bridging this gap won't be easy, but it's what Magnus is attempting in the work I referenced. Essentially he builds a tuple containing the last value received on each channel, waiting until all channels have produced. _______________________________________________ Haskell-Cafe mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell-cafe
