Hey all,

I poked around a bit in the Enum RFCs and I could find (maybe I missed) what's up with this:
enum Foo:string implements \Stringable
{
case FOO = 'bar';

public function __toString() {
return $this->value;
}
}

PHP Fatal error: Enum Foo cannot include magic method __toString
It seems to me that when the enum is a string it is entirely reasonable to expect __toString() to work here and support the \Stringable interface.
Is there a reason I'm missing as to why this is problematic in the engine that's been documented somewhere, or is this an oversight we can look at correcting?
John
