The most recent C++ thing I worked on (not that recent, like 5 years or so ago) was a fairly new project and the people working on it were really passionate about C++. But it was C++ code that ran as a Python library and was using the official Python C bindings. Not sure why we didn’t use one of the unofficial C++ libraries, but the usage of that C library (and such a fundamental one) held things back. We wrote was was modern C++ (at the time), but big chunks would be a completely different style.
