Limit Variable Scope

Generally speaking if you limit the scope of variables as much as possible: * code is more efficient (RVO usage for example) * more maintainable (less to reason about) * more optimizable (constructor/ destructor inlining, etc) * more const correct With rare exceptions.

A dark-mode social media post lists the programming benefits of limiting variable scope: efficiency, maintainability, optimization, and const correctness. The joke is a dry technical endorsement of minimizing scope, with “With rare exceptions” acknowledging that programming rules have edge cases.
