Quite true, but you should also include the last sentence of the section:

"That's all there is to a closure: a subroutine that preserves any lexical variables it's using, even after they become invisible everywhere else." OO-Perl pg.57

Closures are only interesting (for some definition of interesting) when the lexical is invisible.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
