GObject extension propose (GContainer)

[Fontana Nicola <ntd users sourceforge net>]

Hi all,

I'm a GObject based libraries (for UI purpose and not) user and I often need
 a generic container to derive my own types. In my opinion, I think this
 generic container must be included inside the GObject library ... it could
 be used by a lot of derived libraries providing a common approach.

I published my solution - that is, what I am currently using - on
 sourceforge.

http://sourceforge.net/projects/gcontainer/

Is it a good idea? Is something planned in this direction? Am I totally
 wrong?

I need feedbacks ...
Nicola
