I've struggled with this kind of issue before. One of the main benefits of Perl is that TIMTOWTDI, no doubt about it. I know, it's all about context. There's nothing wrong with the rules as they are currently constitued. However, I've found in a number of cases Perl does not do the least suprising thing. The examples above show that while being incredibly flexible, there's a lot of room for a small mistake to yield far reaching, mean, nasty consequences. At what point does TIMTOWTDI make Perl code start to be less readable, and thus less maintainable?

I don't have any preconceived notions about it, I'm just asking the question.

• 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).
