Re: Cannot run revealer.scm example.

I am on debian testing, and the gtk4-demo also stopped working as
expected for the revealers example a little while ago ... what I mean
to say by that, is (a) no animation and (b) the example stops after 
all 9 revealers have been revealed.

However, I don't have any of  those bug/messages here:

        david@aicha:~ 1 $ cd gnu/g-golf/git/examples/gtk-4/
        david@aicha:~/gnu/g-golf/git/examples/gtk-4 4 $ ./revealer.scm 
        [no messages, just an empty line, until closingthe app

Make sure you_do not_ GI GLib nor GObject functionality (refering to
the below part of your message)

Perfect, I use gtk 4.4.1+ds1-3 but it still has no animation
'anymore',so this is an upstream bug/problem

You should not (never) introspect(import) GLib nor GObject, which
are manually binded, for bootstrap reasons - if something you need is
missing, ask for it, I'll double check and possibly implement the
missing binding ...
