Python is likely the best example of this working, however even in Python the boundaries between high and low performance sections are very formal. It's a lot simpler to go in and optimize a piece of code the profiler has pointed out with C++.
I really don't understand the animosity non-C++ developers have towards the language. You can still use Python, Rust, etc if you want. Nobody wants to force you to use C++.
