It has nothing specifically to do with POSTMATCH, you just ran into the multi-concatenation optimization.

#!/usr/bin/perl use strict; # use warnings; use v5.10; sub add_incr_suffix { state $suffix = 'A'; return "prefix-TEXT-" . $suffix++; } print 'Test ' . ( add_incr_suffix =~ /^prefix-*/p ? "${^POSTMATCH}" : '' ) . "," . ( add_incr_suffix =~ /^prefix-*/p ? "${^POSTMATCH}" : '' ) . "," . ( add_incr_suffix =~ /^prefix-*/p ? "${^POSTMATCH}" : '' ) . "\n";

Here is a simpler example that produces different output under 5.26 and 5.30

#!/usr/bin/perl use strict; # use warnings; my $foo; print "test: " . ($foo = 1) . ($foo = 2) . ($foo = 3), "\n";

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