The both assumptions may be invalid in a particular situation. The stronly coupled systems may exhibit collective behavior and development, and it is this collective behavior that must be described, rather than particular structures (which may be essentially not unique). In the strongly interacting system, an object may mutate after the interaction with another object, remaining essentially the same, so that the object cannot be described by a static type, class etc. A new language is required to deal with such general cases. The basic idea will be to make the language absolutely reflexive, so that any construction could be treated as object, class, or metaclass in different aspects. The limit of weak coupling can be assotiated with the internal regions of the regular flows, while the weak interaction between the objects will arise from a small level of mixing present.
