Very true. In hhvm, we tried an enum class to avoid bugs with

There are many ways to get around this, such as user-defined
function or template, or a built-in .valueOf property.
template ValueOf(alias E)
if (is(typeof(E) == enum))
{
import std.traits: OriginalType;
enum OriginalType!(typeof(E)) ValueOf = E;
}
You can call this in a function for use with UFCS.
