Hello,

I would like to get R=46C Karma for my wiki account. My username is: jkro=
on.
The proposed R=46C will introduce Enums with Associated Values for cases =
and is inspired by Rust and Swift.

=46or example it would allow for the following:

=60=60=60
<=3Fphp

enum ApiResult =7B
=C2=A0=C2=A0 =C2=A0case Success(string =24data, int =24statusCode);
=C2=A0=C2=A0 =C2=A0case =46ailure(Throwable =24error, =3Fint =24statusCod=
e);
=7D

function handle(ApiResult =24r): string =7B
=C2=A0=C2=A0 =C2=A0return match (=24r) =7B
=C2=A0=C2=A0 =C2=A0 =C2=A0 =C2=A0ApiResult::Success =3D> 'OK ' . =24r->st=
atusCode . PHP=5FEOL,
=C2=A0=C2=A0 =C2=A0 =C2=A0 =C2=A0ApiResult::=46ailure =3D> 'NO ' . (=24r-=
>statusCode =3F=3F 'unknown') . PHP=5FEOL,
=C2=A0=C2=A0 =C2=A0=7D;
=7D

echo handle(ApiResult::Success('All good', 200));
echo handle(ApiResult::=46ailure(new Exception('Bad request'), 400));
echo handle(ApiResult::=46ailure(new Exception('Server error'), null));
=60=60=60

Regards,
Jordi
