All of these variations seem like things that aren't hard to roll for
yourself, especially with a few good examples in the javadoc.
But if range and rangeClosed really don't feel like enough to you, then
retain the stepped versions (with a different, uglier name) but add an
open/closed argument so it's only one extra method for each of the
primitive types and not two.
rangeFarAfield(start, bound, step, HALF_OPEN);
Ugly enough that people won't use it unless they have to.
