in thread 'our' is not 'my'

I guess that also explains why I can put 'our $var;' in package BB and have this version of $var carried through main. Each use of 'our' replaces any previous alias for the remainder of the execution. I'll have to re-train my brain on what to expect from packages :)

Makes me a little nervous that Perl would allow this without some kind of warning. Also makes me wonder what kind of problems could be made easier using 'our' in this way?

    The point is that Perl is willing to trust you. Your telling it our $var means “I and all my friends in this lexical scope want to use this variable without qualification” (that's why it's the first person plural!). Since it believes that you know what you're doing, it doesn't want to warn you later when you do just what you said that you were going to do.
