Hi Monks,
I have some trouble with the following code: 
use strict;
use List::Util qw(shuffle);
my @train = (1, 2, 3, 4, 1, 2, 4, 4, 1, 2, 3, 4, 1);
my @test = shuffle @train;
# my @test = @train;

Running it with "perl -d:DProf" I get the following error message: "Modification of a read-only value attempted at - line 4." Commenting out the offending line, no error but no shuffled list. With just "perl -w" everything is fine. I get a shuffled list without error.
It seems to me that the func "shuffle" is not profiler friendly.
Curiousity: I'm on Win32 with ActiveState 5.8.8 build 822. With ActiveState 5.8.8 build 820 I can run it with "perl -d:DProf" getting a shuffled list without error message.
Any hint?
Thanks in advance.
