This usage before super call

[wgebczyk]

ES6 disallow to use this before super call.

class Aaa {
  constructor(v: () => number) {
  }
}
class Bbb extends Aaa {
  vv: number;
  constructor() {
    this.vv = 111;
    super(this.vvv);
  }
  vvv(): number { return 0; }
}

The line "this.vv = 111;" must be after super statement.
The super statement also cannot contain this usage.
Compilation to ES6 gives:

class Aaa {
    constructor(v) {
    }
}
class Bbb extends Aaa {
    constructor() {
        this.vv = 111;
        super(this.vvv);
    }
    vvv() { return 0; }
}

So even if TS wants to relax "this usage before super" (which i doubt), then it must fix in generated ES6 code.
