+ * command terminator is semicolon-newline-newline; whenever the backend
+ * sees that, it stops and executes what it's got. If you write a lot of
+ * statements without empty lines between, they'll all get quoted to you
+ * in any error message about one of them, so don't do that. Also, you
+ * cannot write a semicolon immediately followed by an empty line in a
+ * string literal (including a function body!) or a multiline comment.
