Pelemay 0.0.6 has been released!

A new feature of this release is to support String.replace.

defmodule M do
require Pelemay
import Pelemay

defpelemay do
def string_replace(subject) do
String.replace(&1, “Fizz”, “Buzz”)
end

def enum_map_string_replace(list) do
  list
  |> Enum.map(& String.replace(&1, "Fizz", "Buzz"))
end

end
end

This code is 4x faster than original Elixir code.
