Create use dotopdown (or doreverse, name it as you like):

Hi George,
That's correct. I briefly mention the JVM's standard hot swapping
capabilities when running in debug mode. Unfortunately this hot
swapping is mostly limited to changing method bodies and not class
signatures (add/remove method, etc).
Normally this is not even a problem because - as

I am aware of that list. I would be interested in what influence those
languages had on clojure. E.g. what language features Rich borrowed from which
language when he designed Clojure.

I think it comes down to the following:
