Yet another way you can get a repl into an existing process running on the
JVM:
https://github.com/wirde/swank-inject
Disclaimer:
It's a hack
It uses JDI to connect to the process (requires remote debugging on the
target, but no other modifications)
Won't work well for some classloader hierarchies
The Swank repl *doesn't* work well (yet), uses
clojure.contrib.server-socket/create-repl-server
instead
But:
You do get a (remote) repl injected into the application
You can get hooks into any (singleton) instances in the target process
