I see a lot of issues but not a lot of PRs. As a maintainer there is a lot of prioritization going on, and it seems that the things that bother the blog author are not things that bother the maintainers. I also agree with some of the replies on the issues - garbage in garbage out for a function is ok behavior.

One of the cool things about clojure and other languages like this is that these things can often be fixed at runtime - so even if your fix doesn't get accepted you can have a "my-better-fixes" lib you pull in for yourself. A "consistent-set-opts" lib you add to your project.cls for example.
