( #3333=superdoc: print w/replies, xml ) Need Help??
I believe you're running into the "This variable is read-only and dynamically-scoped." aspect of this variable actually working; I take that to mean once it is set in the same scope, it can't be overwritten. Not sure if this a bug or a bug had been fix, either case would explain the discrepency you're claiming.

The following code (perl v5.28.2) seems to do what you want; of course the matches are no longer in the same dynamic scope since the concatentation over all strings is no longer being utilized.

use warnings; use strict; use v5.10; sub add_incr_suffix { state $suffix = 'A'; return "prefix-TEXT-" . $suffix++; } print "Test \n"; print add_incr_suffix =~ /^prefix-*/p ? ${^POSTMATCH} : '', ", "; print add_incr_suffix =~ /^prefix-*/p ? ${^POSTMATCH} : '', ", "; print add_incr_suffix =~ /^prefix-*/p ? ${^POSTMATCH} : '', "\n";
Outputs:
Test TEXT-A, TEXT-B, TEXT-C

In anycase, seems like you may have been depending on a bug for some behavior that is no longer present.

Title:
Use:  <p> text here (a paragraph) </p>

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.
