ES 2017 #private class fields

@GeoffreyBooth sayd: #4552 (comment)

Obviously we need to choose a different syntax than # to denote “private.” Maybe whoever wants to work on that can start a new issue with a proposal? And a PR can follow.

I create a new issue with a proposal:

coffeescript ~name is like javascript #name

private:
@~name
@.~name
this.~name

public:
@name
@.name
this.name

Wherever we can write obj.~prop we can write obj~prop, its both compile to obj.#prop

Example:

CoffeeScript:

class Cat
  
  constructor: ->
    @~name = 33
    return
    
  say: ->
    return @~name

Must compile to:

class Cat {
  #name
	
  constructor(){
    this.#name = 33
  }
	
  say(){
    return this.#name
  }

}

Private methods:

class Cat
    
  ~privateMethod: ->
    
  @~privateStaticMethod: ->

must compile to:

class Cat {

  #privateMethod(){ }
	
  static #privateStaticMethod(){ }

}

Access to another object:

class Point

  constructor: ->
    @~x = 0
    @~y = 0
    return
  
  
  equals: (point)->
    return @~x is point~x and @~y is point~y

Destructuring params to private vars:

class Point

  constructor: ({@~x,@~y})->
    return

  # or short syntax
  constructor: ({~x, ~y})->
    return

Ugly but not the CoffeeScript 3.0
