is it normal for 'boot repl' to take upto 30 seconds to boot up ?

(this is with lots of librtaries)

@qqq yes unfortunately it can take a while, especially if you require a namespace with a lot of dependencies when you start it

if I have a task which modifies the classpath, where do I put load-data-readers!? I keep getting Can't set!: *data-readers* from non-binding thread

Someone on the GitHub page has some questions they're asking in an issue (https://github.com/boot-clj/boot/issues/605). I don't know enough to answer, but I'd be curious to see the answer.
