agustina_s has asked for the wisdom of the Perl Monks concerning the following question:
Hi Perlmonks..
I want to ask something which must be very easy for most of you but really weird for me as I am new in Perl.
When I want to print something which is a reference to an array..
I try to use this :
but it doesn't work. If I print without the ${ }, it will just give me output like :print ${$entry->FTs->elements};
The same thing also happen in hash.. it's just that the output is HASH(...). How should I print the content? Thanks in advancedARRAY(ox1bf614)
