Bug description:Enum case value must be constant
Description:
------------
When testing enums in 8.1 I tried to assign a constant value to a backed
enum. I got a message saying that the value should be constant. That's
very misleading. The RFC states:
"Equivalent values must be literals or literal expressions. Constants
and constant expressions are not supported. That is, 1+1 is allowed, but
1 + SOME_CONST is not. This is primarily due to implementation
complexity. (See Future Scope below.)"
I think the message should say "Enum case value must be a literal or a
literal expression" or constants should be allowed just like they are in
normal classes.
Test script:
---------------
<?php
const A = 'foo';
class Suit {
const Heart = A;
}
enum Suit: string {
case Heart = A;
}
Expected result:
----------------
No fatal errors or warnings
Actual result:
--------------
Fatal error: Enum case value must be constant in /in/sj7b4 on line 10
