Assigning to @$part would work fine if $part didn't already hold a value. As it is, you must either use a separate variable: my $part2; @$part2 = grow($part); or copy the return from the subroutine into an anonynous array: $part = [ grow($part) ]; But I think it would be best if the subroutine just returned a reference to an array in the first place.
