Setup

function P(t) {this.t = t}
P.prototype.m = function(i) {
  if (i > this.t) {
    this.t = i;
  }
}

function P1(t) {
	P.call(this, t)
}

Object.setPrototypeOf(P1.prototype, P.prototype)

class C {
	constructor(t) {
		this.t = t
	}
  m(i) {
    if (i > this.t) {
       this.t = i;
    }
  }
}

class C1 extends C {
	constructor(t) {
		super(t)
	}
}
