💻 Code

class A {
    constructor(...args: any[]) {}
    get myName(): string { 
        return 'A'; 
    }
}

function Mixin<T extends typeof A>(Super: T) {
    return class B extends Super {
        get myName(): string {
            return 'B';
        }
    }
}

class C extends Mixin(A) {
    get myName(): string { 
    // Unexpected Error:
    // 'myName' is defined as a property in class 'Mixin<typeof A>.B & A', but is overridden here in 'C' as an accessor.
        return 'C' 
    }
}

var c = new C();
console.log(c.myName); // will print 'C' as expected though

🙁 Actual behavior

Error in get myName() of class C:
'myName' is defined as a property in class 'Mixin<typeof A>.B & A', but is overridden here in 'C' as an accessor.

It is obviously incorrect because myName is defined as a getter (NOT a property) in either A or B.

🙂 Expected behavior

No error.
