I think if i understand this properly you can see the same thing at work without overload. Try this:

package T; use Data::Dump::Streamer; sub foo { \$_[0] } sub bar { my $x=shift; \$x } my $o=bless [],'T'; Dump($o->foo,$o->bar,$o)->Names(qw(foo bar o))->Out(); __END__ $foo = \$o; $bar = \do { my $v = 'V: $o' }; $o = bless( [], 'T' ); $$bar = $o;

What happening here is that you seeing the difference between copy semantics (what happens with assignment) and aliasing semantics (what happens when you take a reference to an alias).

But i know you well enough to know this isnt a surprise to you, so Im wondering if you could explain in more detail perhaps with a minimal case we can run to see the effect you mean.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
