Enums with interface do not resolve correctly

[haringsrob]

Hey,

I continue to have this issue (#2218), made sure I am on latest master (disabled my wip as well).

I think it is because of the interface as I tried this little test case:

This has issues:

<?php

interface test
{
    public function foo(): string;
}

enum Test: string implements test
{
    public function foo()
    {
        $this->cases(); <--- Undefined error
    }
}

Test::from('bar')->foo(); <--- Method "foo" does not exist

All fine with:

enum Test: string
{
    public function foo()
    {
        $this->cases();
    }
}

Test::from('bar')->foo();

this looks like a parser bug - it incorrectly parses the "base clause" as the "members" node:

also note that it parses the "method" as a "function" instead of a "MethodDecalaration":

compare to a class:

will need to fix in our fork then push an upstream fix

Well, it's mostly fixed in 2220 although it ignores the interface type.
