|

|
|
Common Lisp, types are named by Lisp objects, specifically symbols and lists,
|
||
|
|
called <i>type specifiers</i>. Symbols name predefined classes of objects,
|
||
|
|
whereas lists usually indicate combinations or
|
||
|
|
specializations of simpler types.
|
||
|
|
Symbols or lists may also be abbreviations for types that could
|
||
|
|
be specified in other ways.
