in reply to Use more threads.

I saw a post on comp.lang.perl.misc asking why there is a new threads-shared module available separately for perl 5.8. The poster said that he made some improvements, but it was too big to put into the main perl5.8.8 release. That is weird isn't it? It says 'bless' is now supported on shared refs.

Thats a bit beyond me, but you might find it interesting.

    I saw blessing support in new threads::shared ? yesterday.

    The poster said that he made some improvements, but it was too big to put into the main perl5.8.8 release. That is weird isn't it?

    My reading of that was that the changes were extensive and finished too close to the release of 5.8.8, so that there was not enough time to ensure adaquate testing before release. Releasing it to cpan means that those us interested in playing with it get to do so now without imposing the associated risks (if any) on all users of 5.8.8.

    This way, dave_the_m potentially inlists a bunch of testers to check the changes out before it gets considered as a candidate for the next release. I think its a great idea. My only wish is that threads was available separately packaged also.

    It'd be nice if things like the defined-or keyword could be made available in a similar manner. It seems to have been an inordinately long time since I first heard that was mooted for inclusion and it's still not available :(

      Indeed, I must say that I am much more interested in the //= operator than in threads. Defined-or is useful even for small, single-threaded applications, such as the ones I write every day. Sure, it's mostly syntax sugar (mostly), but it's very *nice* syntax sugar (and, yeah, there are also those few instances where you really don't want to evaluate the left side twice, but that's more of a special case even than threads).

        I once came up with a way of allowing new keywords to be added to the core, such that they would have no affect on the way Perl is parsed unless enabled by using something like use extensions qw[ say ];. I thought that this would be a convenient way of adding potential new features into the language for widespread evaluation without falling foul of backwards compatibility considerations. Unfortunately it wasn't viewed favourably :(
