Yes,
naming has been my major problem with this...in fact to be complete
the name should take into account that with the above definition the
interval is right open

coerceRangeToRightOpenIntervalFrom:to:

verbose, uh?
But if we want to implement the complementary definition

x mod (a .. b]

there is the need for such distinction.
Given the following property

x mod (a .. b]  = x mod [b .. a)

the implementation is trivial:

Number>>coerceRangeToLeftOpenIntervalFrom:min to: max

"x mod (a .. b]  = x mod [b .. a)"


^self coerceRangeToRightOpenIntervalFrom:max to: min



coerceRangeToRightIntervalFrom:to: could be a very nice addition for Point
(and classes implementing \\?)
to make things like the following possible:

(110 at 120) coerceToRangeFrom: (11 at 71) to: (50 at 60) .  ->  32 at 65


i.e. like having an infinite space and recenter position within the view
bounds
see

Morph>>wrap where newX and newY are set.


Another example for wrapping:

TextMorph>>cursorWrapped:  (this is not with Point)



Now the name is hard to select!

inInterval:
inRightOpenInterval:
withinInterval:
withinRightOpenInterval
...


I personally do not dislike nRightOpenInterval:
