perl5ever has asked for the wisdom of the Perl Monks concerning the following question:
There are probably a couple of different aspects to what I mean by 'support'. For instance, CONS cells can be implemented in perl5 by using two-element arrays, but that's not very efficient. Also, it would be nice if all the list processing operators worked on CONS cells as well as on arrays, i.e. map, grep, etc.
All of the major scripting languages seemed to have overlooked this data type.
