C++26: A User-Friednly assert() macro
Summary
The article explains why the traditional C++ assert macro is fragile due to preprocessor parsing rules, introduces the P2264R7 proposal to make assert variadic so it accepts any expression without extra parentheses, and discusses how diagnostics and future contracts relate to its evolution. It notes current lack of compiler support as of early 2026 and concludes the change would improve usability without breaking existing code.
