If you did the right thing and were fully aware of everything you were doing, warnings would be unnecessary. But brains fart regularly. And when they do, you might not even be aware of it were it not for those warnings ... and that puts the risks right off the scale.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:

    [hippo]: That's equal parts clever and horrendous.
    [Eily]: the overload version wouldn't return true with "$x" && !length $x though, I guess
    [hippo]: The more I look at this code, the more $x is a plain old scalar and the more this condition will never be true. I'm calling it a bug at this point.
    [hippo]: Thanks for your input which has soothed my sanity (a little)
    [Corion]: Eily: Sure - if you force both things into stringy things, then you break that magic. But that would also mean that you changed the expression, as now $x = 0.00 will be true instead of false as it were before
    [Corion]: Ah no, at least in my feeble experiments that doesn't change the meaning
    [Corion]: We sell sanity in small packages ;)
    [Eily]: oh, boolean context uses the "" overload if no bool overload has been defined
