Hi

PadWalker is great for identifying and manipulating closed over private variables declared with my.

But what about package variables declared with our?

What's the best way to do this?

Do I have to parse the optree or do we have a Pad for our-lexicals too?

little demo which only works for private vars

  DB<170> sub outer { package BLA; my $my=42; our $our=666; sub { prin
+t "$my,$our" } }

  DB<171> outer()->()
42,666
  DB<172> use PadWalker qw(peek_sub closed_over)

  DB<173> x peek_sub(outer())
0  HASH(0x39d8ec8)
   '$my' => SCALAR(0x39d8dd8)
      -> 42
  DB<174> x closed_over(outer())
0  HASH(0x39d98b8)
   '$my' => SCALAR(0x39d92e8)
      -> 42
1  HASH(0x39d9168)                             # <- What is that,BTW?
   1 => SCALAR(0x39d92e8)
      -> REUSED_ADDRESS
  DB<175>

PS: I'm aware of peek_our(), it just only works from inside the sub.
