If we were starting now we'd probably not be using C at all (and I'd argue
whether or not we should be using gnome/gtk/glib, either).  But alas we
have over a decade of legacy code that's had thousands of man-hours of
work to get us where we are, and it would be a shame to give all that up.

We can play the "what if" games or think about how we could have done
things better if we could start over, but I feel it would be a better use
of our time to look forward instead of looking back.
