I agree that I should not have included references in my list.  However,
references to element patterns cannot in fact be replaced by their
referents, because they are allowed to be used recursively.

I was attempting to compare apples with apples, and so excluded such
larger constructions.

Arise, you prisoners of Windows / Arise, you slaves of Redmond, Wash,
The day and hour soon are coming / When all the IT folks say "Gosh!"
It isn't from a clever lawsuit / That Windowsland will finally fall,
But thousands writing open source code / Like mice who nibble through a wall.
