Nor does C.  Almost everything that most people believe about C is
wrong, because C is not well-defined at any level, so there are
many twisty little C languages, all different.

Richard is perfectly correct that my point was OOP.  C interoperability
does not apply to any derived type with type-bound procedures, which
include finalizers.  Note that this ALSO forbids them from being
passed as data, even if the other language never uses the OOP features
of the type.
