[BUG] exp in class definition

CoffeeScript:

class Cat
  
  [@symbol]: =>

Output Javascript:

class Cat {
  constructor() {
    this.[this.symbol] = this.[this.symbol].bind(this);
  }

  [this.symbol]() {}
}

But must compile like this:

class Cat {
  constructor() {
    this[Cat.symbol] = this[Cat.symbol].bind(this);
  }

  [Cat.symbol]() {}
}

Two bugs:

this in constructor is not this in class body
not need dot after this keyword, this.[exp] is syntax error this.[this.symbol]

Reason:

class {
  [EXP PROP NAME IN CLASS BODY NOT WORKING CORRECT]() {}
}

Start by compiling the CoffeeScript class example from the issue and compare the generated JavaScript with the expected output. Trace the compiler's handling of computed class properties and class-body expressions; done means removing the invalid this.[...] syntax and using the class reference rather than the constructor's this.
