Sorry for the late reply (and possibly in a weird place; I'm not sure Dev's threading implementation is as optimal as it could be) but I've only just found out that Ruby, see, treats a 'range' as Ada does; inclusively, if you use the simple s..e format. An extra dot is required if you want to use the exclusive (i.e. not including the end index) version, s...e. In addition, if you use ::new to create a range, you need to explicitly specify the 3rd, 'exclude_end', parameter if you want the non-default, exclusive, behaviour.
