Why AL0603 for assigning integers to an enum?

[NKarolak]

Bug or feature? Why is warning AL0603 raised when directly assigning an integer to MyEnum, and why not when assigning it indirectly in foreach?

procedure TestAL0603()
var
    MyEnum: Enum MyEnum;
    Integers: List of [Integer];
begin
    // both raise warning AL0603:
    MyEnum := 1;
    MyEnum := Integers.Get(1); 

    // both raise no warning
    foreach MyEnum in MyEnum.Ordinals() do ...;
    foreach MyEnum in Integers do ...;
end;

Don't get me wrong - I prefer it without the warning. So much cleaner ... But then I see no reason why we should get AL0603 at direct assignment.

I think the correct way would be:

procedure TestAL0603()
var
    MyEnum: Enum MyEnum;
    Integers: List of [Integer];
begin
    MyEnum := MyEnum.FromInteger(1);
    MyEnum := MyEnum.FromInteger(Integers.Get(1));
end;

But you can not use FromInteger in foreach, at least not without some (bad looking) overhead:

procedure TestAL0603()
var
    MyEnum: Enum MyEnum;
    MyEnumAsInt: Integer;
begin
    foreach MyEnumAsInt in Enum::MyEnum.Ordinals() do begin
        MyEnum := MyEnum.FromInteger(MyEnumAsInt);

   end:
end;

So in my opinion, it's fine the way it is.
