Here's some test images from a quick patch I've created.

I've let warp take a function so

     warp {
         function{f_bozo(x,y,z)}
     }

is now legal, working syntax.

The attached images use the following function as a
pigment and isofunction.

#declare f_worley = function {
    pattern {
         crackle
         form <1,0,0>
	}
}

#declare worley_warped_bozo = function {
	pattern {
		bozo
		warp {
			function{f_worley(x,y,z)}
		}
		scale 0.2
	}
}
