Primality testing using Cizen.exs

for i <- 2..10000 do
  spawn(fn ->
    # `rem(a, b)` returns the remainder of a / b.
    Dispatcher.listen(Pattern.new(fn x -> x > i and rem(x, i) == 0 end))
    receive do
      x -> IO.puts("#{x} is not a prime number because #{x} is divisible by #{i}")
    end
  end)
end

Dispatcher.dispatch(12) # Insert your favorite number.
