Dmitry Katsubo commented on COLLECTIONS-366:
--------------------------------------------
_rejecting other numbers that do not correspond exactly to the int numbers
contained in the range_
I agree with that. Indeed this is a list of integers, not mathematical range.
I also confirm that my initial implementation (attached to this issue) is wrong
in this respect: should read {{if (o instanceof Integer) ...}}.
P.S. Hopefully this class will be finally included in commons-collections.

> Sometimes there is a demand too have a list, that represents numbers within
> some range (say, [5..10]). If the range is big (millions of records),
> creating a dummy list that holds all instances of objects is too expensive.
> The provided implementation (attached to this issue) solves this problem.
> Nice to have in commons collections.
