A macro with simpler syntax than
defclass' that allows some<br>briefer ways of expressing things. The syntax is more like defstruct.' A
documentation string is optional. Each slot is expressed as either a bare
symbol, or a list of the name of the slot, its initial value, a symbol with the
letters I, R, A, standing for :initarg, :reader and :accessor, and a
documentation string. The symbol, whose package is unimportant, determines the
generation of reader, accessor and so forth; the names are the same as the slot
name. All other CLOS options are processed normally.
In addition, three new class options are defined.
:AUTOMATIC-ACCESSORS means that an accessor is defined for every slot
:AUTOMATIC-INITARGS means that an initarg is defined for every slot
(:NAME-PREFIX <symbol> <separator>) (:NAME-POSTFIX <separator> <symbol>)
prepends or appends
symbol' with separator'
to each slot accessor. The default symbol is the class name and the default
separator is the hypen, in which case the wrapping parentheses are optional.
