in thread Boolean::all gone?

well according to the link http://search.cpan.org/~ingy/boolean-0.11/lib/boolean.pm#AUTHOR

Ingy döt Net <ingy@cpan.org>

i was under the impression that this was the solution to bring a proper boolean technique to perl, but now that it's gone.... no one's using this?

    Given the following documented "Bug":

    Currently, assigning a boolean value to a variable causes the booleanity to be lost. This code dies: 
        $x = true;
    isBoolean($x) || isTrue($x) or die;

    I'm not terribly surprised that such a fundamentally broken module isn't widely used. I've also never found the supposed lack of a boolean data type in Perl to be a problem. I also find the way that isTrue() and isFalse() are defined to look like really bad ideas (because they make the existance of such a fundamental bug not surprising).

    I had never heard of it. Although I tend to avoid Ingy's modules. Inline::C is great, but some of his other modules do weird things that sometimes reach out and bite you.

    I don't think true Boolean types are high up on anyone's list of things Perl needs. Most people seem to get by with truth. 0 (zero) and the empty string ('') are false, everything else is true. That seems to have worked pretty well for the past 20 years :)

      .. I tend to avoid Ingy's modules. Inline::C is great

      I can relate to that. If I had to nominate the "most useful non-CORE module", it would be Inline::C.

      I look at his other efforts ... and then realise that Inline::C hasn't been updated in over 5 years (despite a growing list of bug reports) ... and I shake my head in disbelief.

      Cheers,

    "boolean" is not "Boolean::all"
