I think you may be confused about Dumper output, and perhaps about what's actually in your arrays. In your first example:

\@arr =
[
  1,
  2,
  3,
  [ anna, beth, christie, denise ],
]
[download]

the fourth element in your array is an array ref, not an array. You can only store scalars in an array, so the only way to store an array in another array is to store a reference. The output you show in the second part:

  \[ anna, beth, christie, denise ],
[download]

would actually mean a reference to a reference to an array.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
