- Compound Type Specifier Description:
-
This type specifier can be used only as the value-type in a
function type specifier or a the
special form. It is used to specify individual types
when multiple values are involved.
The &optional and &rest markers can appear in the value-type list;
they indicate the parameter list of a function that,
when given to multiple-value-call along with the values,
would correctly receive those values.
The symbol * may not be among the value-types.
The symbol values is not valid as a type specifier;
and, specifically, it is not an abbreviation for (values).
