Well, I myself try to avoid C++ like the plague :) What I meant was to
have a C++ class which reflect the numpy array, in a sensible manner.
For example, "automatic" memory management (at least as automatic as it
can get in C++), having the member functions of the C class reflected in
C++. The C api of numpy already defines a class, reflected in python.
The job would be to do the same in C++. Eg:
narray A((5, 4), d), B((4, 5), d(
C = dot(A, B)
Of course, to do it right is difficult and would require someone who
know both numpy and C++ very well.
