This post seems to conflate using `throw`, `raise`, etc. with crashing. The idea that 'handling' an error does not involve `throw`/`catch`, `try`/`except` is very strange to me. The exception facility is often the most elegant way to check inputs, and if I remember correctly the Python documentation says as much as well.
