CURRENT-TIME
Print the current time to the stream (defaults to t).

STRING->TZ
Find the OBJ (symbol or string) in +TIME-ZONES+.

Structures

STRUCTURE-PREDICATE
Return the structure predicate name.

STRUCTURE-COPIER
Return the structure copier name.

STRUCTURE-BOA-CONSTRUCTORS
Return the list of structure BOA constructor names.

STRUCTURE-KEYWORD-CONSTRUCTOR
Return the structure keyword constructor name.

STRUCTURE-SLOTS
Return the list of structure slot names.

Classes

CLASS-SLOT-INITARGS
Return the list of initargs of a CLASS. CLASS can be a symbol, a class object (as returned by `class-of') or an instance of a class. If the second optional argument ALL is non-NIL (default), initargs for all slots are returned, otherwise only the slots with :allocation type :instance are returned.

CLASS-SLOT-LIST
Return the list of slots of a CLASS. CLASS can be a symbol, a class object (as returned by `class-of') or an instance of a class. If the second optional argument ALL is non-NIL (default), all slots are returned, otherwise only the slots with :allocation type :instance are returned.

System

SYSINFO
Print the current environment to a stream.


VARIABLE-SPECIAL-P
Return T if the symbol names a global special variable.

GETENV
Set an environment variable.

COMPOSE
Make a new function by composition of previous functions.

DEFCONST
Define a typed constant.
