I believe he wants to do this from C++. I don't know what __main__
is, but I am guessing that his problem is solved by using a
construct like this:
scope().attr("key") = value;
which I believe is just a shorthand for
scope().attr("key") = object(value);
This sets an attribute in the importing module.
value can be any object that is convertible from C++ to Python,
including but not limited to instances of a user-defined classes
X with a corresponding class_<X> statement.
