A fair degree of privacy is gotten by constructions like you discuss. You have very well described the use of closures for private data and methods.

What I really applaud is your conclusion. Perl is not an enforced OO language. Like C++, it is a mixed language with support for OO but no requirement. Unlike C++, perl's OO constructs get by with conventions about what methods may be called reliably. We name private methods with a leading underscore, and we don't care what happens to people who call them from outside.

This voluntary cooperative model of OO gives the screaming horrors to Smalltalkers and other purists, but it leaves a lot of space for us to work in. Mixed model languages are so much more comfortable to work in. The design of a program does not have to be pounded into any One True Shape.

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.
