    The documentation and the code of the module are looking inconsistent. The documentation says:

    $splash->waitVariableX( [$millis, $destroy_splashscreen], \$v1, \$v2} +);

    while in the code

    sub waitVariableX { use Tie::Watch; my ($parent, $millis) = (shift, shift); # @_ has list of var refs

    the arguments have different names (and probably different meaning as well).

      It is the OO Perl. The first argument is the invocant, the second argument is the interval (but according to the documentation, might as well be an array ref). The rest of the parameters are left in @_ to be used later.

      Handling the array ref:

      if (ref $millis eq 'ARRAY') { $callback = Tk::Callback->new($millis->[1]); $millis = $millis->[0]; }

      Handling the remaining variable references:

      foreach my $vref (@_) {
      لսႽ ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ
      The module description stems from the 'Mastering Perl/Tk' bible. Both usage formats are described as valid. I choose the more 'simple' one.

[Corion]: Cosmic37: Ah, see perlfaq4, about How do I compute the intersection of two arrays
[Cosmic37]: I am out of practice; I use Perl for scientific programming for number crunching
[Corion]: Cosmic37: Basically, you read one file into a hash, keyed by your key, and then match the lines from the second file to that hash
[Cosmic37]: note that the two files only have datetimes which may match whereas other data per line is different format in file1 and file2 - is that really intersection?
[jedikaiti]: Hi Monks
[Corion]: Cosmic37: Well, if you want to use only parts of a line for the key, see split or whatever other mechanism to extract the key from the line
[Corion]: Hi jedikaiti!
[Cosmic37]: is there a webpage for full CB for this chat rather than side panel chat?
[Cosmic37]: thank you for advice
[Cosmic37]: peach greets jedi
