I am a bit confused about how an unpack template works. For example: 


#!/usr/bin/env perl

use Modern::Perl;
use Data::UUID;

my $ug = Data::UUID->new;
my $uuid = $ug->create_bin();
say unpack('H*', $uuid); # 767adecd8ed2e11191f4b1907aa0b7e4
 
my ($uu1, $uu2) = unpack('C4 C*', $uuid);
say unpack('H*', $uu1); # Got 313138 Expected:767adecd
say unpack('H*', $uu2); # Got 313232 Expected:8ed2e11191f4b1907aa0b7e4

I expected that 'C4 C*' would extract the first four bytes into $uu1 and C* would extract the rest into $uu2. Obviously I am not getting something here. Would appreciate an explanation

Thank you
