Runtime Error or Exception

The idea
Modern languages divide failures by category — a runtime error too serious for software to handle; an exception recoverable through the language's handling support — and either is "thrown."
In practice
A records system distinguishes the crash it cannot survive from the missing entry it can.
Where people slip
The division decides what code should even attempt.
