An example when the non-intrusiveness is important is when you load up an
entire hierarchy of UI objects from a file and you want to add custom
signals to it. Other solutions to this problem are less elegant.

Another useful non-intrusive feature is the meta signals system. It lets
you manage connections to 3rd party objects automatically. For example it
can be used to add support for C++ functional objects to any C-style
callback API.
