Background:
Say, I have objects of kind E, which operate on structs of kind
M. The problem: if an action is done on a struct, say M42, there
should be also some action done on other structs, which have some
relation to M42, but neither the operating object, nor M42 is
aware of them (and the action which is required), as this would
break encapsulation.
So, I choosed another approach:
There are some describing objects, say of kind B and G, which
hold a specific information (a single property) of all existent M
structs. These objects know which "neighbors" are also affected
in case of some action of E on the struct M42 and can perform
appropriate actions on them, at least on the contained property.
The problem which is still unsolved:
objects of kind E operates on structs M randomly. For this goal,
they have to save the information between their actions, on which
structs they are interested in, to report the ordinal number to
the describing objects.
The saving of ordinal numbers with minimum computational costs
(nogc, even no construction of iota-structs, etc) is crucial.
