Re: Conceptual difference between map and class

It might be worth mentioning that, ultimately, python class instances are syntactical sugar built around an internal __dict__. It gets twistier, since classes are also instances of the base class object. It would be tricky (though I've seen an example...maybe in Joy of Clojure? I think the

I'm going to buck a trend here. Why do you want to do this? (That's rhetorical. Don't feel like you need to answer). One of the fundamental principles behind REST is that it is discoverable. Maybe even that it's explorable. Maybe you aren't building a REST end-point. It's totally possible

Silly ns question

I'm using cider 0.18.0 (which is sweet) and emacs. I just created a new buffer inside a new directory, and it generated the preliminary ns form for me (also sweet). The path to the file under my source directory is "shared/connection-test.cljc". The symbol of the ns that it generated is

Transitive spec generation

I have a spec for an array of 16 bytes: (s/def ::extension (s/and bytes? #(= (count %) 16)) Then I have a couple of other specs that are really just renaming it: (s/def ::client-extension ::extension) (s/def ::server-extension ::extension) I started doing
