//! \brief Transport diagnostic wrapper
class TransportDiagnosticWrapper {
We are doing web-testing in clojure, and in past year our little framework evolved into a DSL of a sorts.
On one hand it is great, we a have consturct like (with-client [name connection & body]), that behind the scenes sets up a virtual machine, registers it as a client of our web-service and destroys it after commands in body are done. I can't imagine we would be doing setup and teardown by hand.
On the other hand it took me a month to get into it (two weeks learning the language, two weeks messing around with the framework) ... and there are still lots of things only our lead-tester knows how to fix, after our devs decide to change something we were relying on for testing.
I am curious, did you already know the JVM? When I learned Clojure, I was also learning the JVM, and for me the JVM was much harder than Clojure. So I would say it took me 6 months to learn Clojure, but much of that time was the time it took to learn about the JVM and all the related Java weirdness.
Either way, 2 weeks is very impressive.
What really helped me that, we had "programing paradigm" course in college, where I learned haskell for 3 weeks, what was enough that anonymous functions, map, reduce and using lists for everything didn't feel new.
