You have just learned what a closure is :-). At least that is my
understanding of one. Perl is "smart" enough using reference counting to
know that the variable may still need to be accessed and so doesn't garbage
collect it. Then when the variable that holds the reference is collected so
is what it referred to (assuming there isn't another reference to that).
Neat huh?
