I'll do that yes, since I failed to convince you it you be a better default for 
of us, not just Guile-CV :)

I hope I can also do that wrt exceptions in an easy way too, I did not look 
with care
to what you suggested, since I thought what Daniel offered was a better 
approach and
that it would be included one way or another in 2.2.4 ... let's see what I can 
with set-exception-printer! then :)


Note that, for info, I named the project Guile-CV, not to refer to existing 
and currently, it does not use Open-CV :) - which doesn't have a maintained C
wrapper :(, but it would be nice to be able to use it 'from Guile-CV', ... one 
maybe ...
