An example of how to use `loop` in the purescript-coroutines library for a single producer and consumer, and for multiple consumers connected to a single producer

	module Connection where

	import Prelude
	import Control.Coroutine (Consumer, Producer, await)
	import Control.Coroutine.Aff (produceAff)
	import Control.Monad.Aff (Aff, later')
	import Control.Monad.Aff.AVar (AVAR)
	import Control.Monad.Aff.Console (CONSOLE, log)
	import Control.Monad.Eff.Class (liftEff)
	import Control.Monad.Eff.Random (RANDOM, randomInt)

An example of using Aff to run synchronous and asynchronous effects, and how to sequentially group effects using parSequence.

	-- Run with `pulp run --main AffParallel`

	module AffParallelExample where

	import Prelude
	import Control.Monad.Aff (Aff, launchAff, forkAll, later')
	import Control.Monad.Console (Console, log)
	import Control.Parallel (parSequence)

	type Piece = String

Why does this Show instance throw "Count not match a0 with type String" (Purescript)

Question

I'm working with this custom data type, and I would to be able to show it if the type of a is showable.

data NonEmpty a = NonEmpty a (Array a)

So I created this type class instance with the dependency that a be showable...

This is a blank starting point for working with PureScript. It can pasted into http://try.purescript.org/ as a starting point for the exercises on PureScript by Example https://leanpub.com/purescript/read

	module Main where

	import Prelude

	import Data.Array (replicate)
	import Data.String (length, fromCharArray)
	import Data.Foldable (for_)
	import Control.Monad.Eff
	import Control.Monad.Eff.Console (log, print)
