As far as Perl is concerned, there is no such thing as “a hash of hashes.”   Instead, a hash consists of a data-structure that allows you to index “a single value” by “some string.”   The pure magic being, of course, that one possibility for “a single value” is:   a reference to absolutely anything at all.

“A hash of hashes,” therefore, is simply a hash in which (as it so happens...) each element is a reference to another hash.   But, as far as Perl is concerned, “it’s a hash, period.”

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.
