Instead of doing this:
defmodule LousyCalculator do
@spec add(number, number) :: {number, String.t}
def add(x, y), do: {x + y, "You need a calculator to do that?!"}
@spec multiply(number, number) :: {number, String.t}
def multiply(x, y), do: {x * y, "Jeez, come on!"}
end
How about this
Hi
As Elixir has reached version 1 there's not going to be a major change of
syntax like this.
You could implement this as a macro in your own project though :)
use MyMacro
def add(x :: number(), y :: number()) :: number() do
x + y
end
Cheers,
Louis
