Now we go on to the body of the function definition. Languide has noticed that the selection is some kind of compound statement, and has remarked on it, in the echo area. It's not important to us at the moment (although it might be a handy clue for a blind user working with Emacspeak); but when we use some of the high-level edits that Languide provides, it will use this information to decide whether the selection is suitable for a particular operation, and if so, whether there is any special optimization it can do.
