There's a fairly simple algorithm to do this that you can write if you understand how recursion and references work. Your function starts with a reference to the root of the hash, the value to add once you find the right node, and a list of keys to find that node. Shift the first keys from the list and look up that entry in the hash, which gives you a hashref. Call the function again recursively with this new hashref, the same value to add, and the remaining keys. Once there are no more keys, you can add the value to the hashref you have, which will point to the right position in the tree. Use a syntax like $hashref = $hashref->{key} to go down to the next level in the hash. By "non strict references" I assume you meant symbolic references, the ones you can't use with use strict. And no, those won't work, because the hashes are anonymous.

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 or How to display code and escape characters are good places to start.
