  This could perhaps be called "advanced feature blindness". That is, people
only see highly advanced features and are blind to the simplest control
structures.
  You just make an identifier from your union:

#declare MyUnion =
  union
  { whatever
  }

  Then you can make copies of that:

object { MyUnion translate <1,2,3> }
object { MyUnion translate <-3,-2,-1> }
and so on.

  If you want to place them in a regular pattern (eg a straight line), you
can use a #while-loop.
