in reply to List into two-dimensional array

You could keep using splice and achieve your goal by using a sub. 

sub group {
   my $n = shift;
   my @rv;
   push @rv, [ splice(@_, 0, $n) ] while @_;
   return @rv;
}

my @rv = group($C, @list);

    That just returns a copy of the original list. You probably meant push @rv, [ splice(@_, 0, $n) ] while @_;.
