On bugs vs input errors:

"I believe this is a misunderstanding of what exceptions are for. 
"File not found" exceptions, and other errors detected in inputs, 
are routine and routinely recoverable.

This discussion has come up repeatedly in the last 30 years. It's 
root is always the same - conflating handling of input errors, 
and handling of bugs in the logic of the program.

The two are COMPLETELY different and dealing with them follow 
completely different philosophies, goals, and strategies.

Input errors are not bugs, and vice versa. There is no overlap."
