How to enable harmony syntax support in coffeescript?

coffeescript, ecmascript-harmony, javascript, yield

Solution

Another way to open the gate to the black dimension is:

co = require 'co'
sleep = require 'co-sleep'

co(`function*(){1`
    console.log 'hi!'
    `yield sleep(1000)`
    console.log 'bye!'
`1}`)()

It's seems to be perfectly valid coffee-script, though, webstorm cofeescript plugin cries about errors, but it works.

Also the following solution(vanilla coffeescript and gulp) is possible:

co      = require 'co'
sleep   = require 'co-sleep'
$       = (cor) -> cor
$yield  = (cor) -> cor

do co $ ->
    console.log "hi!"
    $yield sleep(1000)
    console.log "bye!"

gulp.task 'node-js', ->
    gulp.src config.srcServerJs, {base: config.srcServerJsBase}
    .pipe plumb()
    .pipe coffee()
    .pipe replace(/\$\(function\(/g, '\$(function*(')
    .pipe replace(/\$yield\(/g, 'yield (')
    .pipe gulp.dest(config.dstServerJs)

magic: no errors in IDE :)

Update After trying and reading a lot of stuff about coffee, ecma6 and its future I decided to give up on coffeescript and go with ECMA6 with support of traceur for both node.js and client-side

Problem

I used node.js(0.11.13) with `--harmony` flag and used `function *()` and `yield` keywords. I tried to simplify my development on node.js with help of coffeescript, so far it works great but I went into troubles with `yield` and declaring a generator - it complains about 'reserved keyword yield'. Any ideas?
