:pre conditions, that leverage
the same amount of details in the error messages, but that is always
"turned on".
In the meanwhile, I will use s/assert ;-)

I think a natural place of the :post condition shold be after the argument
brackets (and that should be possible to implement I think):
(defn user-name [user :core/user] :user/name
(-> user :user/name))

Hi there!
Another solution is to use the Micro Monolith Architecture to solve
dependency problems
which also gets you a really awesome development experience!

Polylith is an architecture that has been inspired by the simplicity and
composability of functions.
We asked ourselves the question "what would a system look like if we could
build it with high-level blocks that share the properties of functions?".
It turned out that the answer looks a lot lik
