Always use [closed, open) intervals

Intervals or ranges pop-up everywhere in the programming world. The classic example is picking a start and end date, like you would when booking an AirBnB or a flight. But that's just one example: from slicing a JS Array, to Java's List#sublist and even SQL's LIMIT operator, ranges are everywhere.

Norman Doors: Don’t Know Whether to Push or Pull? Blame Design.
