I recommend that you use the perlbug command line tool to ask p5p to explain the outcome of the following cleaned up version of your program. Include the output.

use strict; use warnings; use feature qw( say ); use Data::Dumper qw( Dumper ); BEGIN { package str; use strict; use warnings; use feature qw( say ); use overload '""' => \&stringify, '.' => \&concat; sub new { my $class = shift; bless([ @_ ], $class) } sub stringify { join '', @{ $_[0] } } sub concat { my ($s1, $s2, $inverted) = @_; return ref($s1)->new( $inverted ? ($s2,$s1) : ($s1,$s2) ); } $INC{"str.pm"} = 1; } sub _dump { local $Data::Dumper::Indent = 0; local $Data::Dumper::Terse = 1; local $Data::Dumper::Sortkeys = 1; return Dumper(@_); } { my $str = str->new('foo'); my $good = "a $str a"; say "good: "._dump($good); my $bad; $bad = "a $str a"; say "bad: "._dump($bad); }

Output:

good: bless( [bless( ['a ',bless( ['foo'], 'str' )], 'str' ),' a'], 's +tr' ) bad: 'a foo a'

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.
