I think it helps to know that Perl4 had no references˛, so none of the - now normal - nested data-structures described in perldsc were available.

With the introduction of Perl5 multi-dim hashes had to be kept for backwards compatibility, but are for most an unknown or obscure feature.

But they are quite handy sometimes, you'd be surprised how many people tend to reinvent something like $h{ join(",",@dims) }= "x" which is essentially the same without a safer separator.°

HTH! :)

°) a former boss was particularly proud to show me his "genius" trick to safe memory ...

˛) a lot had to be achieved with *type-globs (yuck)

Title:
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.
