From CppCoreGuidelines: Rule of Zero: C.20: If you can avoid defining default operations, do. C.52: Use inheriting constructors to import constructors into a derived class that does not need further explicit initialization. DRY forward and using declarations. Miscellaneous: Fix format.sh to output examples with normalised paths in sorted order. Co-authored-by: ArthurSonzogni <sonzogniarthur@gmail.com>
