All a slice is, is a list of elements of the structure.
@array[1,3,5]
is
($array[1], $array[3], $array[5])
And
@hash{$x, $y, $z} = @other{$m, $n, $o};
is
($hash{$x}, $hash{$y}, $hash{$z}) =
($other{$m}, $other{$n}, $other{$o});
So doing something like:
@people{@newkeys} = @$contact{sort keys %$contact};
is doing this:
1. sort the keys of %$contact
2. access the VALUES of %$contact in that order
3. assign to the values of %people, whose keys are in @newkeys
A long-winded expression would be:
@values = @$contact{sort keys %$contact};
for (@newkeys) {
$people{$_} = shift @values;
}
