@mafintosh said most of this, I just wrote it down

how to destroy/end streams in node >= 0.10

• usually you call .destroy() if it has .destroy
• if it doesnt have .destroy you are out of luck and the stream should upgrade to use e.g. newer through2
• in request you call .abort() (this should get fixed to use .destroy())
• .end() tries to end the stream gracefully

what about close

Simply register the two helpers "section" and "yield-section", and start right away!

See example below, using ember-cli:

// Use @include colorize('image.png', red, 0.5)

@mixin colorize($image, $color, $opacity) {
      background: $color;
      $color: transparentize($color, 1 - $opacity);
      background: -webkit-linear-gradient(left, $color, $color), url($image); 
      background: -moz-linear-gradient(left, $color, $color), url($image); 
      background: -ms-linear-gradient(left, $color, $color), url($image); 
      background: -o-linear-gradient(left, $color, $color), url($image); 
}

(function( exports ) {

  function EventEmitter() {}

  EventEmitter.prototype.emit = function() {
    var type, handlers, args, listeners;

    type = arguments[0];
    args = [].slice.call( arguments, 1 );
