I'm working on a clone method for an object (which makes a deep copy of the data structure and all other data structures 'contained' by it).
The standard module Storable will do a deep copy for you with one subroutine call. Might want to check that out.
I'm trying to create a new reference that refers to the same thing an existing reference points to, but is actually a separate reference, so that you get two separately-valued references pointing to the same underlying value.
It's not going as planned.
Here's the code which I expected to work, but doesn't. I'm expecting \$$orig to result in a new reference, but instead it's reusing the original reference that I started with.
So:
$s = "some string"; $orig = \$s; $new = \$$orig;
I believe you just want:
$new = $orig;
You're trying to copy the reference and = generally means copy.
print "orig:$orig, new:$new\n";
