Problem with css3-prefix arguments

[ghost]

I see mixins css3-prefix have 2 arguments, but in some methods calling with more than 2 args.

@include css3-prefix('box-shadow', 0 0 0 1px $colorTwo, 0 0 0 2px $colorThree);

@include css3-prefix('transition', $what: all, $length: 1s, $easing: ease-in-out);

When i tried to use @include transition(); without args, sass fired the error

Mixin css3-prefix doesn't have the following arguments: $what, $length, $easing.
