1449236 - Use explicitOrInferredName() instead of explicitName() in ThrowUninitializedThis()?

Status: NEW

(Core :: JavaScript Engine, enhancement, P3)

Description

[André Bargull [:anba]]

We should check if we can use JSFunction::explicitOrInferredName() in ThrowUninitializedThis(), so we can also use inferred class names in the error message.

Example:
---
class Base {}

class C extends Base {
    constructor() {
        this;
    }
}

var D = class extends Base {
    constructor() {
        this;
    }
}

// ReferenceError: must call super constructor before using |this| in C class constructor
try { new C(); } catch (e) { print(e); }

// ReferenceError: must call super constructor before using |this| in anonymous class constructor
try { new D(); } catch (e) { print(e); }
---

With JSFunction::explicitOrInferredName() the second error message would read "must call super constructor before using |this| in D class constructor".
