No, it cannot. If you { my $var; some_sub(); }, then some_sub() cannot see $var. On the other hand, if you { local $var; some_sub(); }, then some_sub() can. (And that's why you shouldn't local unless you have a clear reason for it and not before you have signed a contract that you clearly understand that perl is not liable if you botch up at that point, and that you accept the consequences.)

Makeshifts last the longest.

    [Corion]: marioroy: Oh, that's always cool, having API-compatible modules. This makes testing and comparing things much easier
    [marioroy]: IPC in MCE::Shared can handle 400k (sends) per second. That's seems a lot for being a pure-Perl module. After making the release, will come back and post a solution for a node by a fellow wanting faster logging.
    [Corion]: While working on WWW::Mechanize:: Chrome, I had the suspicion that AnyEvent was doing something wrong, but I was able to swap it out for Mojolicious and the error persisted.
    [Corion]: Of course, the error was in my own code ;)
    [marioroy]: Corion, start and start_child in MCE::Hobo::Manager return a MCE::Hobo object, whereas P::FM returns the PID. I can have it return the PID though. I tried Hobo::Manager with several P::FM modules, just changed P::FM to MCE::Hobo::Manager and it works.
    [marioroy]: I also have a Hobo driver for Forklift allowing folks to use in multiple classes, no conflicts with one another. That's not possible for P::FM.
    [Discipulus]: congrats marioroy!
    [marioroy]: CORE::wait works well eventhough multiple instances or classes using Hobo::Manager.
    [Corion]: marioroy: I'm not sure what the normal use for the PID is in P:FM, but I guess that most programs just ignore or log it
    [Corion]: Oh, yes, programs could call wait $pid, but if your $pid is an object, then you could add a ->wait method to it and wait $pid would call that automatically "thanks" to indirect object notation
