Documentation of Channels could really use an example

[kshyatt]

http://docs.julialang.org/en/latest/manual/parallel-computing/#channels

The documentation even references an example file. It would be very nice to have short snippet examples of using put, take, isready, etc. in this section for people who are not familiar with Channels. An example of using the Channel in the for loop would also be great!

Agreed. I am trying to figure out how to do this.

  for alert in channel
      println("Received Alert: $alert")
  end

Is this correct?

[kshyatt]

Bumping this if @amitmurthy or maybe @shashi want to take a run at it? (Or do we think the docs are good enough?)

[tkelman]

Or do we think the docs are good enough?

Channels still don't have any code examples, so no

Has been fixed; see #17674
