(defmacro defclass-w-accessors (name direct-superclasses slots &rest options)
"Identical to DEFCLASS, but with one convenience: A slot definition, if being
simply a symbol, will default to a slot with an accessor and init-arg named after the
symbol. The init-arg will be :symbol, and the accessor will be classname-symbol.
For instance,
(defclass-w-accessors PERSON () (AGE
HEIGHT
(NAME :INIT-FORM Unknown)))
```
is equivalent to
```
(defclass PERSON () ((AGE :INIT-ARG :AGE :ACCESSOR PERSON-AGE)
(HEIGHT :INIT-ARG :HEIGHT :ACCESSOR PERSON-HEIGHT)
(NAME :INIT-FORM Unknown)))
