Summary
This episode explores C++26's enhancement to the `=delete` functionality, which now allows adding a reason that appears in compiler error messages. Jason demonstrates how deleted functions help prevent unintended function calls through implicit conversions, and explains how this new feature improves error messages by making them more informative. The enhancement helps developers better understand why certain functions are intentionally unavailable, potentially reducing confusion and improving code quality.
