Summary
This episode introduces C++17's new [[maybe_unused]] attribute, which allows developers to explicitly mark entities that might not be used in certain contexts to prevent compiler warnings. Jason demonstrates several practical applications, including marking function parameters that are only used conditionally, local variables used solely in debug assertions, and functions that might be unused in certain compilation configurations. The attribute helps developers maintain cleaner code by communicating intentional non-use to both the compiler and other programmers, without resorting to awkward naming conventions or comment-based workarounds.
