On a related note: Any ideas why this:
while( substr( $$str, $y * $WIDTH, $WIDTH ) =~ m[((.)\2*)]mg ) { ...
Works (runs to completion, produces the desired results) on 5.10.1, but silently loops forever in 5.22.0?
Looks like a bug fix. expr =~ /.../g attaches position magic to the LHS after each match, to record the current pos() for that expression. If expr is a var or similar this works well; if expr returns something new each time, the old pos magic gets lost.

This similarly loops forever:

sub f { "abc" } 1 while f() =~ /./g;

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.
