I fear a little bit about performance; and as I very often work with huge datastructures, this might become essential. In production systems (win2k, linux, solaris), I still work with perl5.005_03, because it uses less memory than 5.6 or 5.6.1, and the runtime in many cases is much better, too.

If I've got more time, I'll try to extract a short example to show you by code ...

Another thing I'd like to see "fixed" in perl6 is the following beginner-trap:

my $string = "anything";
my $pattern = "\\";
$string =~ /$pattern/; # must be: $string =~ /\Q$pattern\E/
