defrequired and defoptional instead of @enforce_keys and defstruct

[Juan Jose Lopez Tugores]

For example instead of

defmodule Foo do

    @enforce_keys [:foo1, :foo2] 

    defstruct [:foo1, :foo2, :foo3] 

 end

I write

defmodule Foo do 

    @required_keys [:foo1, :foo2] 

    @optional_keys [:foo3] 

    @enforce_keys @required_keys 

    defstruct @required_keys ++ @optional_keys 

 end

But I think it could better be

 

defmodule Foo do 

    defrequired [:foo1, :foo2]

    defoptional [:foo3] 

 end

Hi!

If you would like to propose features to the language, you need to *argue* why those changes are beneficial. Changes to existing language features can cause a huge impact in the community and we need strong reasons for them.

Thanks.

Hi there

Perhaps this could be implemented in a library as a macro, rather than introducing a breaking change into the core language :)

Cheers,
Louis

Hi José the main reason I see is merely estetic and is to avoid retyping the "@enforced_keys" in "defstruct" but you're right: I have not measured the impact on the ecosystem. For that reason, as Louis said,  it could better fit in a library.

Thank you for your feedback guys :)
