Stuff with the Perl Foundation. A couple of patches in the Perl core. A few CPAN modules. That about sums it up.

Not Writing Perl 6

[ #37767 ]

Today I have again failed to build Perl 6 on Solaris. Eventually I managed to get it to compile on an older Linux box. I figured a good place to check out basic functionality was to create a doubly-linked list class and see how easy it is. That's when I discovered a lot of problems just trying to find good examples of Perl 6 code on the Web. Where's a simple class with an object initializer? I think I write something like this:

class Node {
    has $.val is rw;
    has $.next;
    has $.prev;

    submethod BUILD ($self:) {
        $self.!linkto($self);
    }

    method !linkto ($self: Node $target) {
        $.next = $target;
        $target.prev($self);
    }
}

Of course, that's just a stub class, but no matter how I try to write it, I always get a Statement not terminated properly at line 6, near "($self:) {\n" error. Maybe submethods aren't implemented, but I figured I could examine the spectests to see what's there and that's where the real problem kicks in: make spectest uses subversion to fetch the tests from the pugs repository. Our firewall doesn't allow this. I had planned to spend today working with Perl 6, but there are still too many obstacles for just casually playing around. It's getting so much closer I can just taste it, but not yet. Not yet. Damn!

Update: I give up. I've tried multiple workarounds just to get a proper Node constructor up and running and everything is throwing errors :(
