Remove the documentation string from facts?

[ikitommi]

Is the documentation string needed? there is always the testing from clojure.test than can be used for that. There would be less syntax to learn & simpler code.

What do you think?

Probably a good idea. On the other hand, it does not hurt much to have it as an optional thing. There is now some semi-ugly code for guessing if the doc string is present, that would go away if we drop the doc strings.
