It sounds like you're doing something like:

$ perl -E 'my @x = ([qw{a b c}]); say "@x"'
ARRAY(0x7fab41804248)

But you really wanted to do something more like:

$ perl -E 'my @x = ([qw{a b c}]); say "@{$x[0]}"'
a b c
[download]

Please take a look at SSCCE. If you provide us with something we can run to reproduce your results, we'll be able to provide better help.

Also, just showing expected output — without showing the input and how it was processed — serves no useful purpose. Perhaps you accidentally omitted some important information; however, I see nothing in your post that indicates why "('x', 'y', 'z', 8,9,7)" would be expected.
