lispdoc - results for gensym 

(gensym &optional (thing g))
Function: Creates a new uninterned symbol whose name is a prefix string (defaults to "G"), followed by a decimal number. Thing, when supplied, will alter the prefix if it is a string, or be used for the decimal number if it is a number, of this symbol. The default value of the number is the current value of *gensym-counter* which is incremented each time it is used.
Example:
(defun use-new-world ()
  "Make up a new world and use it.
  The world inherits from the current world."
  (setf *world* (get-world (gensym "W")))
  (setf (world-current *world*) t)
  *world*)

(alexandria.0.dev:make-gensym name)
Function: If NAME is a non-negative integer, calls GENSYM using it. Otherwise NAME must be a string designator, in which case calls GENSYM using the designated string as the argument.
  
(alexandria.0.dev:with-gensyms names &body forms)
Function: Binds each variable named by a symbol in NAMES to a unique symbol around FORMS. Each of NAMES must either be either a symbol, or of the form: (symbol string-designator) Bare symbols appearing in NAMES are equivalent to: (symbol symbol) The string-designator is used as the argument to GENSYM when constructing the unique symbol the named variable will be bound to.
  
(alexandria.0.dev:make-gensym-list length &optional (x g))
Function: Returns a list of LENGTH gensyms, each generated as if with a call to MAKE-GENSYM, using the second (optional, defaulting to "G") argument.
