Hi Monks,

In Getopt I have "tlef:s@" => \$optsHash->{tlef}, which could be single or array. I moved to 5.20.2 

 if($self->{tlef}){
   if(@{$self->{tlef}}) {

[download]

If tlef is defined once then I want to check if its an array. Previously if if(defined @{$self->{tlef}}) { was working. Now its deprecated, so if I remove define, I get the cant use string as ref issue. Is there an easy way to check if the command line option from GetOpt is array or single element?

Regards.
