Modification of a read-only value attempted at Captura.pl line 396 (#3)
    (F) You tried, directly or indirectly, to change the value of a
    constant.  You didn't, of course, try "2 = 1", because the compiler
    catches that.  But an easy way to do the same thing is:
   
        sub mod { $_[0] = 1 }
        mod(2);
   
    Another way is to assign to a substr() that's off the end of the string.
   
    Yet another way is to assign to a foreach loop VAR when VAR
    is aliased to a constant in the look LIST:
   
            $x = 1;
            foreach my $n ($x, 2) {
                $n *= 2; # modifies the $x, but fails on attempt to modify the 2
            }
   
Uncaught exception from user code:
