Although my example didn't make much of a case for it, in some cases it may be useful to have both the original doctest code and the translated code. If the translation went awry, this could help the user ascertain what happened. > I like this. Please open up an issue. Done: Doctest error messages could display the actual doctest code #8889 https://github.com/elixir-lang/elixir/issues/8889 -r -- You received this message because you are subscribed to the Google Groups "elixir-lang-core" group.

Re: [elixir-core:8537] [Proposal] Simplify @spec def and @spec defp for efficiency and maintenance purpose
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

[elixir-core:8537] [Proposal] Simplify @spec def and @spec defp for efficiency and maintenance purpose
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:
defmodule LousyCalculator do
@specdef add(x number, y number) :: {number, String.t} do: {x + y, "You
need a calculator to do that?!"}
@specdef multiply(x number, y number) :: {number, String.t} do: {x * y,

We can probably have the code show exactly that, no need for a new doctest entry. I like this.
