I have been experimenting a lot with spec during December, and I really
like it. On the downside, the syntax is very verbose, compared to prismatic
schema. However, reuse is much simpler than for schemas.
I disagree with this decisi
Could someone explain why the first doesn't work and the 2nd does?

What am I missing?

There is one big difference: In Erlang, fail as early as possible is the
norm. In Clojure it is almost the opposite.
Many errors in Clojure code will result in nil, and most operations acce
I moved my own definition of defn to a separate project, and then it works.

"lein uberjar" works.
When I run "lein run", th
