I keep on seeing people saying this, and here I am thinking to
myself, "Gee, and here I would only give myself even odds
of getting #6 right." I know what the operator is for, I
know how to use it perfectly well as a sort
know how to use complex combinations to do sorts on
But do I know whether the comparison function is
supposed to return a 1 or -1 to sort to say that the left
side is smaller than the right this time...? I could
guess but I never
remember that. If I really need to know it, I can look it
up any time. All that I need to know the vast majority of
the time is that whatever way it goes, sort and the
comparison functions agree on how it is done. (And this
tidbit is of a kind I find hard - for instance I still have to think about whether in a LEFT JOIN the table you want to fill in blanks for should be on the left or the right.)
EDIT AUG 2009 Somehow this node got badly messed up. I've filled in the end with what I think is my original thought, but it is unlikely to be right. :-(
