- * approach a Schwartzian Transform, after Randal Schwartz. We
- * construct a temporary array, where each element is an array
- * containing our sort key along with the filename. We sort this array,
- * and then extract the filename from the result.
- *
- * sorted = Dir["*"].collect { |f|
- * [test(?M, f), f]
- * }.sort.collect { |f| f[1] }
- * sorted #=> ["mon", "tues", "wed", "thurs"]
- *
- * This is exactly what <code>sort_by</code> does internally.
- *
- * sorted = Dir["*"].sort_by {|f| test(?M, f)}
