Re^4: 'our' is not 'my'

in reply to Re^3: 'our' is not 'my'
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.

[Corion]: ambrus: Yes, ideally the module would do all that nasty stuff for me and give me a way to ask it what the current situation is
[ambrus]: Corion: you could also consider using some wrapper over the multi interface of curl, I think Net::Curl might be a good one, since implementing enough of what it expects from the event loop might be easier than a full AnyEvent interface.
[ambrus]: Corion: you could also consider using IO::Async and its POE driver and some HTTP module for it, but I don't know if that would solve your problems with AnyEvent+POE
[ambrus]: Corion: wait, you didn't say POE. You said Prima, let me look up what that is.
[ambrus]: Corion: have you considered just writing an AnyEvent integration for that thing?
[ambrus]: Or perhaps pushing schmorp to write one?
[ambrus]: Also, searching for an existing one on CPAN obviously
[Corion]: Prima, which is mostly cooperative multitasking
[ambrus]: Corion: also (sorry for the obvious ideas) consider running your HTTP thing in a separate process from Prima (separate thread won't work well if you need a perl interpreter on both sides)
[Corion]: ambrus: Yeah, that's the alternative which I considered, at least for file I/O, but as I only want to simply do HTTP from my Prima app :)
