Hi, this doesn't seem to be working actually, I tried the range 2-5 and it didn't happen. But I've already made me a workaround with [expr~] anyway, and I also tried another option similar to this for the range of -1 and 1. I bet there is a simple workaround this way too to make it generic to any range, but I wouldn't say it is "trivial" and "simple", it can make the quest for an object like this sound silly or banal, but I still think (even by having found a workaround mysef) that it'd be just really simpler if there was an object for it. So I'd like to make the suggestion for one. It could be an abstraction like this.
