This is conceptually different to a Monad in Haskell. Monad bind operations have short circuit failure, so in the example above all of the operations would have to succeed or none of them would. cond-> looks like a useful function but you have to hold the state in your head at each point to debug it. What happens if two steps change the type from int to string then the follow step requires the string, but if the previous step fails you would get an int? Seems it would be very prone to runtime surprises

cond-> doesn't, but some-> short circuits on nil. Similarly, with expressions in Elixir short circuit on a failed pattern match. https://clojuredocs.org/clojure.core/some-%3E https://clojuredocs.org/clojure.core/some-%3E https://hexdocs.pm/elixir/Kernel.SpecialForms.html#with/1 https://hexdocs.pm/elixir/Kernel.SpecialForms.html#with/1
