Distribute obfuscated code with a REPL

I have written a program that is well suited to be run in the REPL. I want to distribute it without making the code available. What are my options? It is OK if it means some REPL functions won’t work. I realize it’s probably not going to be as obfuscated as a binary but the more the better.

Thanks and cheers!
