Re^2: lexicals are all the same scalar and never go out of scope?

in reply to Re: lexicals are all the same scalar and never go out of scope?
in thread lexicals are all the same scalar and never go out of scope?

By your logic, the following never deallocates the referenced array:

use Devel::Peek;
$x = [];
Dump($x, 1);
$x = undef;
$x = [];
Dump($x, 1);

But that's just not true. It just got reallocated at the same address. Looking at the address is not meaningful.

(I'm not saying that it isn't the same scalar. I'm saying you haven't shown that it is the same scalar.)
