Yeah but they are overkill - small fast and integrated into core Gnome
without dependencies on perl and python would be a lot better, faster
and leaner on memory usage. We don't need a full blown language to do

No it allows some of us to extend functionality rather than it being
fixed and static. Theres nothing wrong in allowing for further
customisation (like sawfish allowed lisp to be used to script in

Not really mozilla's XUL is used for its desktop apps.The XPCOM it uses
is similar to bonobo. It allows u to create powerful scripted apps
really fast. Its a really neat technology that Gnome should adopt.

If it were incorporated into core Gnome rather than being a little heard
of add on then it would get used.

 Why? HTML allows various scripting languages to be incorporated. An XML
language spec would be a hell of a lot quicker for using your preferred
language than writing new languages or bindings.

Stuff the bindings - they just create extra work every time a library
changes. Say I wanna use VBA - so what ur telling me is that I have to
create a whole new interpreter for VBA complete with all the necessary
language bindings - thats crack. A simple generic scripting interface
with syntax defined by XML is a quick and easy way to getting integrated
scripting into Gnome with the least overhead. The only objects that the
scriptiong language should use are bonobo and/or glade.
