Wow, congrats!  And thanks!

I've created a package description for Guix (see attached), with some
patches (also attached).

How is is that I overlooked this thread?  I spent last Thursday --
reluctantly -- adding webkitgtk bindings to guile-gnome and debugging
an initial browser test.  With Guile-GI it worked in minutes! :-)

One of the patches adds the web browser example and the last one adds an
editor example...but that segfaults in the key-press-event handler.

I've just noticed test/closures.c -- is that intended for handlers like
key-press-event; are they different from `clicked'?

Patches also on my `wip' branch: https://gitlab.com/janneke/guile-gi.git
