Ummm me again!

Here is another use that boggles my mind:

    	scale 10 + z * 30

Without testing I would assume the following 2 lines will do the same as
above: 

    	scale <10,10,10>
    	scale < 1, 1,30>

or am I reading it wrong.

I believe the use of x, y and z (also t, u and v for that matter) are
to make things more readable, not more complex.

I guess this goes with any language, where one can create complex
shortcuts that become not so obvious to read later on. 

I'm not in my cup tonight, please excuse me :)

Thanks
