Note that currently in a Perl subclass of a \f(CW\*(C`Gtk2::Editable\*(C'\fR widget,
a class closure (ie. class default signal handler) for \f(CW\*(C`insert\-text\*(C'\fR
does not work this way.  It instead sees the C level \f(CW\*(C`($text, $len,
$pos_pointer)\*(C'\fR, where \f(CW$pos_pointer\fR is a machine address and cannot
be used easily.  Hopefully this will change in the future.
A \f(CW\*(C`signal_chain_from_overridden\*(C'\fR with the args as passed works, but
for anything else the suggestion is to use a \f(CW\*(C`signal_connect\*(C'\fR
instead.
