That prints only the length of the first subarray, the one corresponding to the key `"k"`. Let's do better and use the `each` keyword to print the length of each subarray. `my %g = (k => [8, 2, 10, 2, 1, 3],l => [10, 7, 9, 0, 1]); %gkey = sort keys %g; print 0+@{$g{each %gkey}}, "\n";` [download]	[reply] [d/l] [select]
