What, no Perl? Well, using threads in Perl 5 is rather painful. I’ve never had to use threads with Perl 5 (beyond making DBI thread safe a few years ago) and I’d be happy to never have to.

On the other hand, I believe people are using threads successfully, though I’ve no handy links for you beyond pointing out that CPAN offers a number of solid Thread:: modules.

All this reminded me that I’d never got around to reading Parrot’s Concurrency design document. So I did. I liked it as a statement of direction, though it’s a little thin on the interaction between schedulers.

I couldn’t find many interesting links discussing both Parrot and Erlang. An O’Reilly Radar post called Parrot and Multi-threading from September 2007 was hopeful.

I’m still wondering if Parrot could act as a virtual machine for Erlang. I think that would be a valuable test case for the quality and scalability of the concurrency design.
