| What about my idea? Can't there be a module, say called | *interpreter* which | you can add and remove definitions from on-the-fly? | Something that would put you tighter in the loop. Without | having to go back | to the editor edit stuff, reload from interpreter, choke on | error, see what | went wrong, etc. Just scratch some code on the CLI, see what | you've defined | so far, edit the current module, and evaluate what you want | to. So the CLI would have to have a way to show you what the current "interpreter" module was, and let you edit it. How does that differ from an editor? This smells like a tarpit to me: once you provide a basic editor, everyone will want more features. Better, surely, to use an existing editor? S
