libscalar-listify-perl 0.03-2 (amd64 binary) in ubuntu eoan

 A lot of Perl code ends up with scalars having either a single scalar value
 or a reference to an array of scalar values. In order to handle the two
 conditions, one must check for what is in the scalar value before getting on
 with one's task. Ie:
 .
  $text_scalar = 'text';
 .
  $aref_scalar = [ 1.. 5 ];
 .
  print ref($text_scalar) ? (join ':', @$text_scalar) : $text_scalar;
