a commentary
During the great alphabet famine of two thousand aught six, column names were abbreviated to near-non-readability. In order to automate tests of [newsystem] reports against [oldsystem] reports, we're retaining those column names here. You're welcome.

Synthesizing functions in javascript... practical applications?
From David Laing & Greg Malcolm's excellent javascript koans. I'm wondering: What are practical uses cases for this function synthesizing in javascript, where this approach would be preferable to all other possible approaches:
it("should use lexical scoping to synthesise functions", function () {
function makeIncreaseByFunction(increaseByAmount)
{
var increaseByFunction = function increaseBy(numberToIncrease)
{
return numberToIncrease + increaseByAmount;
};
