Well, still comparing to C structure, GObject without properties is 2.5 
slower and with 5 properties it's 3.5. The difference looks quite big, I 
suppose it's due to additional checks those could be disabled but I'm 
not sure it's done by default.

Anyway, this is not a fundamental change it will be easy to what is 
difference at the end.

It's the best theoretical situation but I think in practice it's a lots 
of signal for nothing.

Yes, I think it's more reasonable.

I'm completely satisfied with this but I think I need to try it to see 
how it fits in details.

I think so. I can be useful to distingue both type of property for the 
compiler using a typedef. But it's not very important at this point.


I will try to implement this so we can discuss about something more 
concrete. If you have new ideas, just present them, the interface is 
still in development.
