 . If in a local scope (e.g. in a function definition or a let form), a lookup is done to see if it names a local binding (e.g. a function argument or let-bound name). If so, the value is the value of the local binding.

Note that class names normally denote class objects, but are treated specially in certain special forms, e.g. `.` and `new`.
