One quick question: "The set of all strings we can derive from a single axiom by repeatedly applying a single rule is called a transitive closure, or just a closure." Where does the name "closure" come from? How is this related to a variable-binding-capturing "closure", as in &closure in

{ my $foo; sub closure { $foo++ } }
(I know, I'm getting into lvalues here.)
