The question made sense.

dieing is the right response when something occurs in code that the programmer was not expecting or hasn't got around to handling.

On the other hand, as graff points out, when an error condition can be anticipated then testing for that error and producing an alternative response is a great thing to do.

For example, in a commercial web app, it is conceivable that a database handle may not be obtained (high load, some tweap in operations decided to take the db offline, sunspot interference). What to do in the situation.. die and leave the user hanging? No; probably a more adequate response is a "website is busy, please return back soon!". If the webpage just died then it would be particularly unpretty and unprofessional.

Of course, if that multiline if..elsif..elsif.. statement falls through to a final else that should be impossible, then die and die spectacularly.. the programmer needs to urgently tend to the impossible!

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).
