I just saw the string Alexandre Moreira started a few days ago. No need to repeat anything from there. I guess it's just worth noting that he isn't the only one that wants to (read-line) from a function invoked on the REPL. My use case is similar to his. I have functions that take several arguments. It's easier on the human brain to ask for the data through a series of prompts instead of using a long function call. I'm also toying with the idea of using readline to add tab completion to some of my prompts. I haven't tried Readline, yet, though.
