I just understood the other reason why gmm++ doesn't overload operators, not 
even assignment operators. gmm++ hasn't fully decided whether it was a 
standalone library or a glue between other existing libraries. So it tries to 
be easily extensible to interface with any other library. The problem is then 
that you can't overload assignment operators from outside a class.

This is where we can add something. We, contrary to gmm++, don't aim at being 
easily extensible from the outside.

Just defining our "branding" :)

No worry, this one is easy. There's also good documentation about this coding 
pattern.

Me too, as I'll be defending my phd thesis in one week! Thanks for the kind 
words.

Cheers,
