I have used the following logic to identify blessed things.
$is_blessed = $x =~ /=/; # ASSERTED: ref($x)

Somewhere years ago I got the impression that a stringified reference was defined to be of the form commonly seen:

Classname=Implementation_type(Hex_address)
or
TYPE(Hex_address)

But perlref for 5.8.0 says: Using a reference as a string produces both its referent's type, including any package blessing as described in perlobj, as well as the numeric address expressed in hex.

This doesn't guarantee the =, the (, the ) or the order of the other elements.

Is there any usage of stringified refs in existing code that would inhibit an alteration of their format? Or am I just a odd man out.

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 or How to display code and escape characters are good places to start.
