Less error prone? Five studies cited by McConnel found that routine size was either inversely correlated with error frequency, or not correlated at all

The studies could be right.

Less changes required? Another study finds that code needs to be changed least when routines average 100 - 150 lines.

The study could be right.

On the other hand, we have your unsupported opinion.

Yeah. Unsupported. Maybe even wrong.

But I have found small things to be easier to maintain. More flexible. Easier to change, even though more lines change. Easier to re-use. Small subs are usually easier to read and understand.

Easier to document. This is worth a lot.

Whether or not short subs work for you depends on more than Perl alone. Short subs are better than long subs, much like how short sentences are better than long sentences. The long ones may seem more brilliant and more intelligent, but the shorter ones are clearer and much easier to read.

Guess why books for children use short sentences. Guess why most programming introductions start with printing Hello, world.

Of course, programs/modules with short subroutines are harder to create (since it requires more design) and slower.

I do not know of any study that supports my opinion.
I do not know of any study. I don't care much about studies either, since few are done using the right context and variables.

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