different identifier for constructor and class

[GlenDC]

With source being:

(function () {
  class _0xf79654 {
    constructor(_0x18ba7a) {
      this.target = _0x18ba7a;
    }
    greet() {
      console.log("Hello " + this.target);
    }
    setTarget(_0x121c44) {
      this.target = _0x121c44;
    }
  }
  const _0x431fd3 = new _0xf79654("world");
  _0x431fd3.greet(), _0x431fd3.setTarget("reader"), _0x431fd3.greet();
}());

(From your classic javascript deobfuscation streaming series, for which a lot of thanks!!! made it all clear)

the following code will make the code incorrect:

const $script = refactor(source, commonMethods);
$script.normalizeIdentifiers();
console.log($script.print());

as it will output the following:

(function () {
  class $$mellowMode {
    constructor($arg0_eatableSaving) {
      this.target = $arg0_eatableSaving;
    }
    greet() {
      console.log("Hello " + this.target);
    }
    setTarget($arg0_abashedHunger) {
      this.target = $arg0_abashedHunger;
    }
  }
  const $$farTeapot = new $$lackingDude("world");
  $$farTeapot.greet(), $$farTeapot.setTarget("reader"), $$farTeapot.greet();
}());

where as you can see the class is now $$mellowMode, but the constructor is $$lackingDude.
