One response touched on it briefly, but I'm not sure what probl
This is second reply suggesting monads (the more the better). Do you
have any sources or examples (smaller the better) of the same problem in
a monadic and non-monadic way?
Thanks

Monads, I knew I cannot avoid them after all. I've tried digging into
the two main clojure-monad tutorials but got kinda lost, repeatedly.

In my opinion one should only catch those exceptions

Hi all
I am trying to figure out some systematic and clear way how to handle
exceptions in clojure and their bubbling up through the call chain.
Let me illustrate it on some code examples (not executable, just to show
the principle).
(defn get-from-io [p]
(access-external-source p))
