Get/Set syntax

[zmthy]

Would a bit of syntax for getters and setters be a good idea? Its use would obviously make it incompatible with implementations of JS that don't support them, but that's the case with using them in the JS anyway. It would just be a little nicer than throwing defineGetter all over the place.

I don't think that non-standard extensions belong in mainline CoffeeScript, but you could certainly start a "rhino" branch that provides convenient syntax for goodies like this. The issue with putting it on the mainline is that it complicates the grammar, and reserves syntax that we might later want to dedicate to other purposes, in order to support a feature that many people won't be able to use.

Closing the ticket.

Here is my getters_setters branch. Some examples from the test file:

obj: {
  set value: (val) ->
    @val: '' + val + val
  get value: ( -> # Anonymous functions are converted to proper getters
    @val + @val
  )
}

class Obj
  constructor: ->
    @val: 0

  increment: ->
    @val: + 1

  set value: (val) ->
    @val: val

  get value: ->
    @val

Six years after, with all ES6 discussion, @StanAngeloff's proposal looks more compatible to the reality and strongly necessary.
