At this point, generic code should just never use opDollar unless it specifically tests for it, and usually, there's really no reason to do that rather than just using length at this point, much as it's far more aesthetically pleasing to use $. But ranges really should support $ just like arrays do, so the current state of things is definitely annoying.
The most common uses are [$..$] and [x..$]. I think those should simply be fixed to take(0) and drop(x) from the range primitives. They are as aesthetically pleasing, generic for any ranges, and efficient for arrays.
