Compass font-face mixin

gistfile1.scss

      @mixin font-face(
        $name,
        $font-files,
        $eot: false,
        $weight: false,
        $style: false
      ) {
        $iefont: unquote("#{$eot}?iefix");
        @font-face {
          font-family: quote($name);
          @if $eot {
            src: font-url($eot);
            $font-files: font-url($iefont) unquote("format('eot')"), $font-files;
          }
          @if $weight { font-weight: $weight; }
          @if $style { font-style: $style; }
          src: $font-files;
        }
      }

Is this the correct use?

@include font-face("this name", font-files("this.woff", woff, "this.otf", opentype), "this.eot")
