Can I promisify @ in coffeescript?

dog.coffee

Promise = require 'bluebird'

module.exports = 
class Dog
  _size: null
  _remains: null

  constructor: (size) ->
    _size = size
    Promise.promisify(@)

  _kill: ->
    @_implodeAsync(_remains)
      .then(@_explode)
      .catch (e) ->
        console.error e

  _implode: (remains) ->
    # gross stuff
    remains

  _explode: (remains) ->
    # gross stuff
    remains
