Modula-3 has some additional features: Exceptions, Objects, Garbage
collection, Template modules, Partial hiding of type information.
Modula-3 makes something different: It uses structural equivalence, that
is, if two records contain the same fields with the same names they are
equivalent. Thus you can't define two distinguishable record types simply
by defining one twice.
