Really? Then what do you mean by "embedded abstraction" now?

This is complicated by the fact that many subpatches use $-variables to 
access what belongs to their parent.

Ah, in the last mail I forgot to think about the evaluation order of 
object constructors in a patch. That's going to be a big problem, or at 
least an "ugly" one; sort of like the kind of reason that pushed the 
authors of C to require declarations to be above the uses of functions (so 
that the compiler doesn't have to parse things twice...)
