in reply to More efficient dereferencing of a subroutine return

Are you aware that Perl has list-context?

my @ARRAY=subroutine(); sub subroutine { my @array=("one", "two"," three"); return @array; }

If you still need to return an array-ref in other cases just check wantarray in a condition to see if a scalar is expected.

return wantarray ? @array : \@array;
