Let me clarify: you're editing a function in the file. You're not 100% sure it's correct. The function is a long one, so you put some blank lines between parts of the function to organize it. The function is a single top-level form. You copy-paste the function (not the whole file!!) into the REPL so that you can experiment with it. BOOM! your REPL gets confused by the empty lines inside your function, which it thought was ENTER-ENTER. You are then forced to re-edit the function to insert \ into empty lines to prevent the REPL from confusion. So: using the same reader at REPL and at file is useful for this use case. > > b) A smart repl could notice when a line is at the same indent as the > previous expression, and eval the previous form.
