Why? Nested classes are not a problem in OPL, more in C++ (multiple
inheritance!).

Nested classes are a problem because of the pointer overhead.
For example 100 nested classes will require 100 pointer lookups and thus
100 instructions.
Please give example code of what you consider "nested classes".
So a good question would be: what capabilities do classes have which
objects do not have ?
Better question: what common capabilitiers are implemented differently
in Object and TObject?
Try to answer that question first, then we'll see what you didn't
understand.
