The Schwartzian transform is a general technique or pattern that is applicable to much more than sorting problems. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]

The Schwartzian transform is a general technique or pattern ... ... you might wanna check on that ... After looking at a bunch of Schwartzian Transforms, I must admit that they all seem to have sort stuck somewhere in the middle. I think what was bouncing around in the back of my mind when I wrote that were echoes of two important design patterns: a series of list-consuming/-producing functions (which may or may not include `sort`!) that feed each other seriatim to produce a final output; and the notion of memoization. I'd have to say now that while the ST (or decorate-sort-undecorate, or whatever) embodies those two patterns and is an important sorting design pattern, it's certainly not a general design pattern (or technique, or whatever).
