It seems that what we've lost with unicode/7 is the speed of character references. In other words, this:

I ran a simple test to completely reverse a string, not line by line, but character by character, something like: repeat with i = length(string) down to 1; put char i of string after result; end repeat and it was orders of magnitude slower even than Alex's line-by-line solution. I subbed byte for char, and it doesn't seem to matter or change anything. Until that issue is addressed, it seems any solution that depends on repeated character or byte indexes into a string is going to suffer from the highway line painter's problem: he paints fewer lines each day as he gets farther and farther away from the paint bucket.
