  It'd be nice if there was a table of contents on the Perl Hacks page -- even a tentative one. The rough cuts version would be much more enticing if I knew exactly what was in the book. :-)

    What sort of time penalty is this sort of technique going to introduce?
    
    function calls are already pretty expensive, but depending on how you are implementing this I imagine it could result in a lot more of them. Would this be correct?

      Efficient, safe (no source filter) and concise may be too much to hope for, but would be wonderful. Requiring a Scalar::Util from this millenium seems fair.

      You are correct. It's as fast as it can be without a source filter and without using XS (though I can already think of a way to make it faster with XS).

  I have a little module that does exactly that for a little while now and didn't think anyone else was that crazy :)
  
  I played the game even a bit more in the last weeks:
  
      sub foo :Method( Int $foo, Object $bar! ) {
              self->baz();
              print class, ': ', args->foo;
      }
  
  Called via:
  
      $object->foo( foo => 23, bar => $bar_obj );

    "args" returns just a container object, that uses autoload to simulate accessors. That's just to capture typos. It's mostly following the Perl 6 signature idea (at least the current one).

    Hmmm, it may pair nicely with Moose [cpan.org]: although the latter claims not to be a Perl 6 implementation in Perl 5, it is admittedly heavily inspired by Perl 6 itself, and to some extent imports Perl 6 semantics, with special emphasis on OO features, in Perl 5. Also, it seems that unlike e.g. v6 [cpan.org], it is much less experimental a

  Heya c, do you plan to release Attribute::Method on CPAN? I'd love to see it there, esp. if you have an XS implementation to do the magic lickedy-split!

    Good idea. Keep bugging me about it; I don't have time in the next couple of weeks, but I'll experiment with the XS version.

      Well surely you can get the pure Perl version out in the meantime, eh?
