Tip #2 from the Basic debugging checklist: print the value of the $_ variable in your foreach loop. Does it contain what you expect?

print "$_\n";

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)

    [Lady_Aleena]: The whole line is push @line, ref($list_addition ) ? @$list_addition : $list_addition if $list_addition;
    [Lady_Aleena]: And I forgot to do the array check, I'm such a doofus today.
    [Lady_Aleena]: push @line, ref($list_addition ) eq 'ARRAY' ? @$list_addition : $list_addition if $list_addition; #trying again
    [shmem]: Discipulus: yummy. I like those. Didn't have them for some time now, forgot the name. Should go get some...
    [shmem]: Lasy_Aleena: correct, although for clarity I'd use an if() block, not a statement modifier
    [shmem]: this allows you to add an else if maintainance makes it neccesary
    [Lady_Aleena]: shmem, okeydokey.
    [shmem]: ...or logging or debugging or such
