:buried treasure: n. A surprising piece of code found in some
program. While usually not wrong, it tends to vary from {crufty}
to {bletcherous}, and has lain undiscovered only because it was
functionally correct, however horrible it is. Used sarcastically,
because what is found is anything *but* treasure. Buried
treasure almost always needs to be dug up and removed. "I just
found that the scheduler sorts its queue using {bubble sort}!
Buried treasure!"
