The absence of strict, warnings, and taint don't necessarily imply a bad script. I'll grant that they increase the chances that a script doesn't do what are commonly accepted as "bad" things, but they are not necessary. There are some I know that code under strict and warnings, but then remove them when the final cut is made so as not to be anti-social and assume that everyone wants these module loaded. If there was only One True Way to code Perl, those modules wouldn't be modules, they'd be part of the language spec.


Feel the white light, the light within
Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come

    No, it doesn't. Each is useful for different purposes.

    • strict is useful is you plan on ever making a change to the thing as it will decrease the time you need to do so safely.
    • warnings is useful is you are a less-experienced developer.
    • taint is useful if you are taking information from an untrusted source.

    Of these three, I would add strict and taint. Warnings are ... annoying in production code. I take it out in my CPAN stuff. I would add taint because I'm not sure what Win32::OLE is going to return to me. I'd like to see if Perl trusts it before I do.

    Being right, does not endow the right to be rude; politeness costs nothing.
    Being unknowing, is not the same as being stupid.
    Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
    Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
