Good point. Maybe all of these parameters should be options:
Array.range() -> 0, 1, 2, 3, ...
Array.range({ start: 3 }) -> 3, 4, 5, 6, ...
Array.range({ end: 5 }) -> 0, 1, 2, 3, 4
Array.range({ step: 3 }) -> 0, 3, 6, 9, ...
Array.range({ start: -2, step: -1 }) -> -2, -3, -4, -5, ...
etc.
The defaults of start and end and the comparison operator depend on the sign of
step.
