If the choice is between importing a module when it's necessary to do
a copy-by-value and implementing it for all classes, I'm not certain
that I'd prefer the latter. As some others have mentioned,
copy-by-value is not something very many people will need every day,
and if they do it'll often be because they don't take proper advantage
of the language. No PEP from me, at least not as it stands now.
