Wonderful piece. A small typo: "Fuctor" in the first code sample. Edit: I think "dependant" is also a typo. Apparently in British English it is used to mean a dependent in the sense of a child who relies on a parent for support, but when it's used as an adjective, "dependent" is still the correct spelling, even in British English.
