Neither do I. Aperiodic tiling is pretty unsuitable for procedural 
object generation.

It is possible, but as demonstrated by the crackle pattern (which is 
aperiodic as well) it can eat memory like mad under certain circumstances.

Um... no, you still misunderstood:

intersection {
     object { A }
     union {
         repeat { x, y*2, z }
         object { B }
     }
}

Same construct should go for merge{} of course.
