We pass const std::vector<foo> &bar which semantically allows a copy to be made of the data (a copy from a python representation to the C++ representation). If you use std::vector<foo> &bar The copy cannot be made (since changes to bar would need to be reflected back into python). > You can look in gr_ofdm_mapper_bcv to see one example of how we > did this.
