Thanks for your input, Christian.  Some specific comments:

Yes, there might be more API changes in the future when I tackle a new
subset of gtk+ and add overrides for it.  But in general, these changes
will make the binding API more Perlish and more backwards-compatible
with Gtk2.  This process can be accelerated (and could even be finished
already), if more people looked at the bindings and contributed patches
for missing pieces.

We're actually sticking very closely to the C API, even more so than
Gtk2.  There's just a thin layer of mechanical translation necessary to
get from C to Perl.  For Gtk2, it's described in
<https://metacpan.org/pod/release/XAOC/Gtk2-1.249/lib/Gtk2/api.pod>.  We
need to port that to Gtk3.  Patches welcome.

This is not how you use a Gtk3::TreeModel (of which Gtk3::ListStore is
an implementation).  You need to first create an iterator and then use
it to put data at its position in the list.

  my $model = Gtk3::ListStore->new ([qw/Glib::String/]);
  my $iter = $model->append;
  $model->set ($iter, 0 => 'Foo');

This is identical to what you'd do in C.
