  In fact, the povray SDL has currently very poor means of achieving good
modularity.
  You can't make modules (classes, structs, whatever) with public interfaces
and private attributes and implementations, you can't construct your own
abstract data types, you can't make objects (ie instances of these data
types) and so on. You can't even construct the most basic types of dynamic
data containers (eg. lists, trees and so on; and yes, I know about arrays,
but they are currently just too clumsy and inefficient as *dynamic* data
containers).

able to dynamically allocate them (and having references to these allocated
objects) would be an enormous step in versatility and modularity. Structures
and references cover most of the features needed for user-defined abstract
data types (although without interfaces they are still not very modular).
