Passing a function to Enum.map in Elixir -

i'm learning elixir , wonder if there better way pass function pointer enum.map. have code:

defmodule mymodule      defp greet(person)         io.puts "hello " <> person     end      def main()         people = ["manuel bartual", "el hijo de la tomasa"]         enum.map(people, &greet/1)     end  end 

it works fine, wonder if there way instead of using &greet/1

more idiomatic be:

def main   ["manuel bartual", "el hijo de la tomasa"]   |> enum.map(&greet/1) end 

1. you should not use parentheses when no arguments required in function.

2. the pipeline operator (|>) 1 of idiomatic elixir features. says, take result evaluated , call following function passing result first argument.
