Maybe it's so. Or maybe you run my code in your deps. As you can see, there is at least one Clojure dev who thinks so.

I found spec very useful and damn expressive (and I miss it in other languages), but again that's runtime. I know Rich says such errors are "trivial", but they waste your time (at least mine).

To each their own. Some people (not me) say that Rust's pedantic compiler feels like bureaucratized waste of time akin passing through medieval Turkish customs. For me personally, working with Clojure dialects feels extremely productive. Even writing in Fennel, which is not Clojure, but syntactically somewhat similar is much faster for me than dealing with Lua. Even when I have to write stuff in other PLs, I sometimes first build a prototype in Clojure and then rewrite it. Although it sounds like spending twice the effort, it really helps me not to waste time.
