    ... and you don't even need the '+' on the  += operator:

    >perl -wMstrict -lE "my $s = 'abababa'; my $t = 'aba'; ;; my $c = map /(?=$t)/g, qw(abababa ababa); say $c; " 5
      and you don't even need the '+' on the += operator:

      Of course I don't. Much nicer!

[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
