The return value on the function in C++ is of the wrong type :) I agree though. I used these tricks a lot in scientific computing. Go to the world outside and people are just unaware. With that said - there is a cost to introducing those tricks. Either in needing your team to learn new tools and techniques, maintaining the build process across different operating systems, etc. - Python extension modules on Windows for e.g. are still a PITA if you’re not able to use Conda.
