If you're arguing that the default choices are inappropriate and that the choices should be updated to reflect current Perl programming practices, I'd say that's generally correct (though there are, as I mentioned, a number of things you should, in general, do unless you are a highly-sophisticated programmer and know exactly what you are doing and what risks you are taking).

There is, however, a certain amount of handwaving in your argument against static analysis as a technique in itself. You say you "do my analysis dynamically". What does that mean? As far as I can tell, it means that you decide what to do as you write, determining as you write whether or not you will use a given construct.

For your bareword file handles example, does "I can safely use this bareword filehandle because I know I haven't used it anywhere else, and I'm sure that no module I've used uses this filehandle either because I've read them and made sure" capture the process?

Because that's still static textual analysis - you just happen to be using your brain and not a program to do it. If "dynamic analysis" means something else to you, it would be interesting to hear more about that.

• 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).
