This wouldn't work very well for arrays that concatenate the same but have different values. Consider:
@one = (undef, 1, 2); # "12" @two = (1, undef, 2); # "12" @one = (12, 3, 4); # "1234" @two = (1, 2, 34); # "1234"
The Array::Compare module basically does a join() using an unlikely delimiter (like a pipe character or \0 or \255). Unfortunately, my own benchmarks typically put a "brute force" comparison faster than Array::Compare (sometimes significantly, depending on the amount and type of data in the two arrays), especially when dealing with numeric items in the array. Conversions of data types to strings plus string comparisons tend to be expensive in bulk. If you're working with string data, it might not be so bad.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
