According to the specifications for this project:

The only characters that are allowed (on the same input line) to be immediately before or immediately after an Atom token or a Dot token are a whites-pace, ‘(‘, and ‘)’. For example, (QUOTE (4 .6)) is invalid and the interpreter should reject it with an error message.
