...being bitten by the optimisation...

Not in my particular case. The real-life code is more complicated, as I'm sorting arrays of arrays on an arbitrary column, and the comparators are more that just straight string or numeric compares. Hence I have a number of routines that know how to sort the contents of a column, and I associate each column with a sorter.
