Heureka! found out that the C++ standard library exposes a cross vendor C++ ABI, which amongst others allows to show object code names and type-IDs in the language-level, human readable unmangeld form. Of course, actual application code should not rely on such a internal representation, yet it is of tremendous help when writing and debugging unit tests.
