Something that I've always wondered - why is ClojureDocs not updated? I've
never tried to contribute to it - is it particularly difficult? Is it
impossible for users to add support for new Clojure versions? If so, who
runs it? Could it be turned over to the community?

Is json/decode returning a lazy seq? If so, you're constructing it inside

I have gone the dynamic var before, played well with ring handlers.
Why ?
Because I wanted to ensure consistency between reads to the

So just having the configuration and read the root value at different

I like the dynamic var approach. It even allows to enforce that submodules

As far as possible, I think it is best to try and minimise mutable global

Here are some thoughts about versioning and examples that were driving
my github-wiki idea:
- Incompatibilities between Clojure versions are getting fewer and smaller.
- This suggests that jumping from 1.4 to 1.6 will probably be a lot
smaller than a jump from 1.2 to 1.3.
- This implies that
The GPL incompatibility comes from the choice of law clauses I think.
It is worth mentioning though, that you can combine GPL code and
Clojure, since GPL has an exception for a standard interface of a
programming language. You can write GPL code in most languages, and this
does not require that
