Re: copying an array

[Aaron Craig]

As long as we're on the topic, what's the story on efficiency between using 
an array and an array ref.  Ex:

sub PassAnEntireArray(@)
         {
         my(@array) = @_;
         ...do some stuff...
         }

sub PassAnArrayRef($)
         {
         my($ar) = @_;
         ... do some stuff...
         }

I assume passing array refs (and hash refs for that matter) would be faster 
and more efficient -- does anyone have any definitive answer?
