- for all functions, except when GIL option (not implemented) is here we use a triqs::py_stream, which redirect the stream to python sys.write - so that a simple C++ code with a std::cout print its output in the notebook... - NB : it only works for the code within the cell. If it calls another function on the lib which uses cout, print is not redirected. Designed for simple tests.... - cerr not (yet) redirected. (useful ?).
