About perl closure.

[pswd]

I have little idea about what are closures for perl?
Is it just a function maker that returns a reference of subroutine?

Could anybody tell me what it is and show me some examples?

Thanks in advance!

I think the thing that makes a code-ref a "closure" is that any
enclosing-scoped lexical variables appearing in them have their ref-counts
incremented, and thus can't be freed until after the closure itself is
destroyed.
