module that produces an array/arrayref from a scalar value or array ref
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;
