Hi all, Coming from python, I use dataclasses <https://docs.python.org/3/library/dataclasses.html> a lot to tie complex collections of data together. I like using them in combination with type hints so that it's clearer to me at a glance what kind of data a function is processing. When my data starts to look like a dict of dicts of lists, I turn to dataclasses to help my simplify.
So far in my Clojure journey, I've stumbled across two features that could help me do something similar. First are datatypes <https://clojure.org/reference/datatypes> (deftype, defrecord), and second is using maps with spec <https://clojure.org/guides/spec>. Based on my reading, using spec to define types seems like a really flexible system that does built in testing for me. I was surprised to read that specs can't quite be treated like types though: https://ask.clojure.org/index.php/10464/can-i-use-spec-as-type-hint. Maybe the intention is to use the :pre and :post keys in a function's options as type hints? I'm curious if I'm thinking along the right lines here, or if there are other language features I could be looking at. Also curious if anyone has suggestions for books or articles that explore data typing options in Clojure.
