Richard Hainsworth has started the third stage of revising the POD6 standard to the new RakuDoc standard: RakuDoc revision open to comment. This invites anybody, both inside and outside of the Raku Community, to comment on the proposed definition of RakuDoc, either to the blog post, on /r/rakulang or in the associated problem solving issue.
