The value is also needed to be known at compile time

static assert(Foo.one.order == 0);
static assert(Foo.two.order == 1);

It's not possible to take a runtime enum value and produce its index in an enum without some runtime overhead.

Another issue is that `e.order` is already valid code, meaning call `order(e)`.
