This exists in CFFI (see ffi.new_handle()).  More generally, wouldn't
it make some sense to try to bring cppyy closer to cffi?  It is a
change of some of the basics, so only suitable for people without an
existing code base.  What I'm thinking of is if we could consider a
cppyy-like interface as an extension of the cffi interface, like C++
is an extension of C, or if it doesn't really make sense.


A bientôt,

Armin.
