For "driver has fallen asleep with foot on the accelerator pedal", stopping the car might be a better solution.

Not really. Wind down the window; play music loud; vibrate the seat or steering wheel; a strident bonging sound; all would be preferable to bringing the car to a sudden halt in the middle of a motorway.

If an undef in a variable would led you to deleting every row in a database table, it might be better for the uninitialized warning to be fatal.

It's hard for me to imagine how that would occur, but if it is a possibility, then I might resort to use warnings FATAL => 'uninitialized'; within some limited scope(s); but never FATAL => 'all'.

I routinely eliminate/guard against all warnings in my code as I go along; but when they do occur unexpectedly, seeing whether they are 1-offs or repeated, whether once they start, they persist or are occasional transients; and where the code goes and what other knock-on warnings arise as a result; all assist in the postmortem of working out what went wrong and what to do about it.

Even more so when, for example, you get an unhandled transient warning induced by bad data in a long-running, unattended process.


With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

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.
