in reply to Concurrency in Perl

What about perl6 junctions as a concurrency operator? I don't know if it was the intention, but functions like "all" seem like they could be put to good use as parallel data constructors (see also Connection Machine LISP). For example... 
$ans = 7 + all(1,3,16)

...could spawn off three threads, one for each addition calculation.

    An excelent point, though I'm not sure we can take it as far as LISP can. There has been some research of late for transparently doing parallel processing in functional languages, which is a really big deal. They can do this because statments in functional languages tend to be highly expressive and self-contained.

    For that to be usable in Perl, the rest of the language has to play nicely, too. To do that, the language probably wouldn't look much like Perl anymore. I suspect that a supporting library will still have to be used.

    That would be a very cool idea. It would cause hard to debut errors. It would be very heavy-weight. It would make basic things like handling signals very difficult. But it would sure sound cool.

    Cool isn't always worth it. :-P
