in reply to and vs &&

To eliminate doubts about the right hand condition evaluating to an anonymous list with one entry of the value 0, which evaluates to true I would like to append the following;

$ perl -e 'my $a=(1 == 1) and 0;print "$a\n";' 1

    Where do you see a list in that code?

      I never saw a list, but as parentheses are also used to enforce list context someone might percieve (0) to be 0 in list context. I hope that explains my cryptic clarification :)

[Lady_Aleena]: marioroy, I can't decide whether or not to move my RolePlaying:: Random:: modules to just Random::. I'm not as sophisticated as most here.
[marioroy]: Naming things can be difficult, sometimes more so that the actual code :)
[karlgoethebier]: Lady_Aleena: You need to jump to some conclusion
[Lady_Aleena]: And what would I rename RolePlaying/Random .pm to if I move all the RolePlaying/Random modules to just Random? Random/Util.pm Random/Base.pm, maybe lowercase the file name to indicate it is a bit different? I don't know yet.
[marioroy]: What does Random do?

[Lady_Aleena]: karlgoethebeir, I finished another project tonight, making a module which printed stop printing. It was a headache and a half.
[karlgoethebier]: Lady_Aleena: Try it!
[Lady_Aleena]: marioroy, it has 3 subroutines which can be fed data to generate random things. See here.
