Easy-to-use CSS3 mixins for Stylus (includes linear-gradient)

mixins.styl

vendor(prop, args)
	-webkit-{prop} args
	   -moz-{prop} args
	    -ms-{prop} args
	     -o-{prop} args
	        {prop} args

border-radius()
	vendor('border-radius', arguments)

box-shadow()
	vendor('box-shadow', arguments)

transition()
	vendor('transition', arguments)

transform()
	vendor('transform', arguments)

transform-origin()
	vendor('transform-origin', arguments)

user-select()
	vendor('user-select', arguments)

background-linear-gradient(startPoint, startColor, startInterval, endColor, endInterval, deprecatedWebkitStartPoint = false, deprecatedWebkitEndPoint = false)
	background-color startColor
	if deprecatedWebkitStartPoint && deprecatedWebkitEndPoint
		background-image -webkit-gradient(linear, deprecatedWebkitStartPoint, deprecatedWebkitEndPoint, color-stop(startInterval, startColor), color-stop(endInterval, endColor))
	background-image -webkit-linear-gradient(startPoint, startColor startInterval, endColor endInterval)
	background-image -moz-linear-gradient(startPoint, startColor startInterval, endColor endInterval)
	background-image -ms-linear-gradient(startPoint, startColor startInterval, endColor endInterval)
	background-image -o-linear-gradient(startPoint, startColor startInterval, endColor endInterval)
	background-image linear-gradient(startPoint, startColor startInterval, endColor endInterval)

I realize this is a pretty old mixin list, but it does pop-up on the top of google's results.
The gradient function already generates the appropriate styles - maybe it's because I am using the nib extension.

background-image linear-gradient(startPoint, startColor startInterval, endColor endInterval)
    background-color startColor
    background-image linear-gradient(startPoint, startColor startInterval, endColor endInterval)

This works nicer in this scenario, otherwise you will get A LOT of extra/wrong CSS properties.
Thanks for the nice mixin !
