> I don't think monkey patching is required We're talking about a repl here, not just a basic shell. You'll need to be able to redefine functions and everything else at runtime so a repl is all you need to run your program. A lisp with a standard repl is running miles around any editor/ide with debugger support, as the workflow with repls, especially ones that can nest on exception and so on, is much faster.
