Why is that? Never understood the complaint about slow Clojure startup time. Usually the context is either your local development environment, where you start the process once until you're done for the day, or you're deploying on a server and 5 seconds vs 10 seconds doesn't make that big of an impact. Short-lived CLIs aren't really suitable for Clojure in the first place, you'd use something like Babashka for that.

So why is the "slow startup" actually a problem? I don't seem to hit that issue ever myself, wondering what kind of situation people find themselves at where this hurts.
