An incorrect answer gives me feedback on why my thought process was wrong. A program that dies in the middle just means my typing is not so good.

Remember, most of your time is spent with a broken program rather than with a working program. Once it works, you don't think about it anymore. Getting to that working state is what programming is.

Good dynamic systems don't just die, they halt on the error and fix them on the fly in the debugger. Most of my time is spent on a working program, not on a broken one.
