Fragility? Those exhaustive compiler checks are anti-fragile. There's a binary - either your compiler tells you early on where you need to adapt your code, or your automated test suite / customers will tell you in integration / production. Your code is likely to break either way, the question is how early / cheap would you like the fix to be. Code which is cheaper to fix is less fragile QED
