in reply to Maintainable Code?

If you are using well-documented code, then I see no problem with including "grown-up" Perl concepts. You might want to include a reference in the comments to a book (complete with page number) or website (Perl Monks?) that will explain the "grown-up" Perl concept you are using.

If you continuously dumb down your code, then how are they ever going to grow up as a Perl programmer?

    In The Mythical Man-Month Brooks said, "Show me your flowcharts and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowcharts; they'll be obvious."

    I interpret this to mean, "Show me your data and I can understand your code."

    Basically, if you document what your data structure should look like, what the the keys at both levels should be as well as the value of the second level keys, then maintenance should be a snap.

    I use the following notation for hashes (I probably should just use the format that Data::Dumper uses but I like this, too)

    |->key1
    |     |->key1.1 = value1.1
    |
    |->key2
    |     |->key2.1 = value2.1
    |
    |->key3
          |->key3.1 = value3.1
    
    It sort of represents how I've visualized hashes.

      I typically phrase that as "Data Structures are Algorithms" - a pun to Nicolas Wirth fully intended.
