Uri is occasionally confused. :-)
There's a school of (mis-)thought that "a coderef is a closure". I
don't know how that got started, but it's wrong. A closure is created
only when lexical variables go out of scope. So a coderef without
external references is *not* a closure, and a named subroutine *can*
be a closure.
