Identical to CL:DEFCONSTANT except that the global constant variable NAME is
bound to VALUE at compile time so it can be used in #. reader forms.
Additionally, if the DEFCONST form is evaluated a second time, the constant is
not rebound if the new value is EQUALP to the old.  CL:DEFCONSTANT requires
the two values be EQL to avoid undefined behavior.

Calls ERROR with an argument that indicates a required &KEY or &OPTIONAL
function argument was not supplied.  For example, the following function will
signal an error condition for a missing :AGE or :ADDRESS argument.

(defun foo (name &key (age (missing-argument)) (address (missing-argument)))
  ...
  )

A (MISSING-ARGUMENT) form also useful as the value of a slot :INITFORM when the
slot is required.  For instance, the following class definition ensures that a
value is supplied for SLOT when an instance is created:

(defclass foo ()
  ((slot
    :accessor :slot
    :initform (missing-argument))))

The type (UNSIGNED-BYTE 8).

The type `(SIMPLE-ARRAY OCTET (,LENGTH).

Creates an OCTET-VECTOR containing OCTET-COUNT octets.  If INITIAL-CONTENTS is
not supplied, each element of the vector is initialized to zero.  Otherwise,
the vector is initialized to the contents of list INITIAL-CONTENTS.

Converts STRING into an OCTET-VECTOR by UTF-8 encoding each character.

Converts OCTETS, a vector of UTF-8 encoded octets, into a string.

Does PREFIX match a prefix of SEQUENCE?

Does SUFFIX match a suffix of SEQUENCE?
