Mechanisms identifying, implying or interpreting theorems between intuitively "similar" notions should be discussed in general.
As of the current Mizar, I would include among them the
ClusterImplementation,
TypeImplementation? and the
RedefinitionMechanism?.
However more is probably needed to avoid frequent painful reconsidering in more advanced theories, when different aspects of the discussed mathematical objects have to be used (there are many examples of this, I just wrote
RelationsAndGraphs).
Additionally, we probably do not want to sacrifice the clean set-theoretical semantics of Mizar, to solve this (e.g. as in IMPS) by various
InterpretatonTheories?.
