I smell a lightning talk! Seriously, this would be a cool follow up
because I don't keep up with these kinds of developments in Perl.

Also relevant would be anything to do with Perl threading, AnyEvent,
Coro, etc.  I don't know that much about Perl threading, mainly
because it was when searching for a good threading solution in Perl
(for my needs) that I discovered Qore.

I asked the language developer once if Perl inspired his syntax, and
he claimed to not be that familiar with Perl. I still don't believe
that.  I do know that the language parser and runtime is written in
C++ (and is embeddable), so I am fairly certain the similarities with
Perl are on the surface only. He did tell me he used the Perl syntax
highlighting in vim for Qore, so that made me a little suspicious, too
:).

I have imagined that an inline module interfacing Perl with Qore for
the purpose of threading would be neat. I don't know the first thing
about writing an Inline module that would provide for this, but would
be interested in playing around with something like that. This is one
of the things I wanted to briefly discuss at the conclusion of the
intro talk.
