Hi George_Sherston

This already happens as the code below shows: 

my %hash=(a=>1,b=>2,c=>3);
my @list=@hash{qw(a b c d e f)};
print "\t$_:",defined $list[$_] ? $list[$_] : "undef" foreach 0..$#lis
+t;
__END__
    0:1    1:2    2:3    3:undef    4:undef    5:undef

Undef is returned as with any hash lookup where the key is undefined. BTW I wrote a module called Tie::Hash::Trie (which I have yet to upload anywhere, life got in the way :-) which amongst other things alows this to be changed to any arbitrary value. Let me know if you want to see.
