There is some in testgtk.pl that I slowly is porting from C to perl.
Patches are always welcome. Preferably with tests/examples.

It has been discussed before. 
Data should be stored in 1 place only IMHO
duplication of data is slow and dangerous (gives buggy code).
Properties is stored in the GObjects before we even start
wrapping it so it's a no-brainer.
I experimented with tie but could not get tie and bless
working together.

I seem to recall that Gtk+ has builtin mechanisms for 
listing properties.

Guillaume did not comment on the '-' vs '_' issue,
Gtk+ documentation says '-' so why use anything else?
