On invariants

[Lars Ivar Igesund]

The specification says that invariants can be part of both modules, structs
and classes, but are only discussed closer in the context of classes, and
then in such a way that it sounds like they are _not_ available for modules
and structs (or at least not meant to be used for those). What is the true
intention and reality here?
