There should be a class with a boolean variable and a signal, which is emitted when
the state of this variable changes.  Objects of this class should be combinable with
standard logical operations.  They should probably be refcounted, like std::string,
to simplify handling.  All the rest belongs to Gtkmm.

Maybe I should write a (non-complete) implementation, so it is easier to understand
what I mean, yes.
