Perl6 - Rakudo #22

Hello, I've just read the Rakudo#22 announcement (http://rakudo.org/node/57), and there is a lot of new improvements. In my opinion, the most important is the first one:

"Rakudo is now passing 32,582 spectests, an increase of 17,085 passing tests since the September 2009 release. With this release Rakudo is now passing 85.0% of the available spectest suite".

Wow! 85%! This is very impressive! But, what does this mean?

1. We are running fast to the 1.0 release

2. The spectest is not complete

3. The remaining 15% is complex

4. All options (1-3) are true
