in reply to (tye)Re: Unusual Closure Behaviour
in thread Unusual Closure Behaviour

Says tye:
First, neither of those are closures. They are both examples of static variables and named functions. The term "closure" refers to a code reference that also carries along some variables. In neither of these case is the $x being carried around in a code reference (in part because no code references are being used).
There is indeed code reference. It is stored in the symbol table for the main package. It points to a CV, just like any other code reference, and the CV has a pointer to the pad, which does have the $x variable captured in it, just like any other closure.

So yes, it is a closure.
