Actually, I must be missing the distinction. You're saying that the programmer would use the command line invocation ... programmatically? Something like... 

  system("archive_tar.pl --tar $tarball --destination_path $some_path"
+);

[download]
instead of... 
  $tar->extract($some_path);

[download]
? I'm not sure I see how this is a clear winner.
