I have really come to enjoy the ideas and syntax offered by the P5EE Style Guide.

In the guide, they offer this for plural vs singular variable naming conventions: 
---

Arrays and hashes should be plural nouns, whether as
regular arrays and hashes or array and hash references. Do
not name references with ``ref'' or the data type in the
name.

    @stories     = (1, 2, 3);      # right
    $comment_ref = [4, 5, 6];      # wrong
    $comments    = [4, 5, 6];      # right
    $comment     = $comments->[0]; # right

By consistantly using a system like this throughout your programs, there won't have to be question about whether a scalar contains something like a string, or if it's a reference to an array or hash. As the guide suggests, references would be named in a plural fashion.

FWIW, I'm now using (or at least attempting to) this guide for all of my programming habits :-) Have fun,

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


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
