Well, subroutine calling should be a lot cheaper in perl 6, so there ought not be much difference between starting a new block and starting a subroutine. (That's the plan, at least. Whether we can pull it off is another question entirely)

As for #3.... the AST that the parser builds up will be accessible in some fashion, so the sort of macro transformation you have in mind could work on that, basically working on your parsed code as a series of symbols rather than as a series of characters, which'd make the transformation conceptually simpler.

[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
[marioroy]: Just documentation edits is all that remains. Hobo::Simple provides foreach and forseq with identifier capability -- all transparently supporting array, hash, file handle, and seq 1 .. N.
