You may be better served by the Readonly module*. It allows you to
make variables into constants:
Readonly @nav_tabs_list => ("<div id='header'>\n",
etc.
);
Any attempt to modify @arr will throw an error. What you have is a
constant reference to a mutable array. It is still legal to say
NAVTABSLIST->[0] = "ha ha, I changed you";
But to answer your question try
#!/usr/bin/perl
use strict;
use warnings;
use constant ARRAY => [1,2,3,4,5];
print @{ARRAY()}, "\n";
This works because the constant ARRAY is really the function
sub ARRAY() { return [1,2,3,4,5] }
