If you want solid code in C++ you (essentially) have to only hire people who are good at their job, or accept a long runway where lambdas would simply be taught instead of the inferior methods/patterns they are intended to replace. I have yet to see a C++ codebase which was good while not written by people who are essentially C++ experts, or through in-depth code reviews by such, for all code. I understand finding the talent may be hard, but then the C++ volume might need to be decreased and replaced by something less demanding, or the code will likely be anything but solid.
