Talking about Gazpacho I'll share with you the way I plan to implement
signal_autoconnect in Gazpacho:
1. First check if there is a method named
[on|after]_widgetname__signalname and if so connect the signal
'signalname' to the widget 'widgetname'
2. Then check if the glade file has any signal definition (specified in
Gazpacho signal editor) and then also connect these.
So basically, we wouldn't need the signal editor and all connection
could be done from the source code of the user program. Why don't
removing Gazpacho signal editor?. Well I can think on at least one
scenario where it could be usefull: connecting two signals of two
different objects to the same signal handler.

Go for it!
Seriously, I think we don't have enought signal introspection in pygtk
(or even GTK) but generating xml files with that info and making
Gazpacho use them should no be hard.
