Agreed, lets not make the same mistake in GtkBuilder.

Note that an enhancement to libglade was included to
this patch (that was never applied):
  http://bugzilla.gnome.org/show_bug.cgi?id=161903
... which allows you to specify that your user_data
string is infact a symbol to be dlsym'd and its pointer
passed to the callback... just a piece of code we can
learn from...

It would also be nice if the user could decide whether
the signal is 'swapped' or not.
