find-symbol  string &optional package ⇒  symbol, status
string—a string.
package—a package designator.
The default is the current package.
symbol—a symbol accessible in the package, or nil.
status—one of :inherited, :external, :internal, or nil.
find-symbol locates a symbol whose name is string in a package. If a symbol named string is found in package, directly or by inheritance, the symbol found is returned as the first value; the second value is as follows:
If the symbol is present in package as an internal symbol.
If the symbol is present in package as an external symbol.
If the symbol is inherited by package through use-package, but is not present in package.
If no such symbol is accessible in package, both values are nil.

 (intern "NEVER-BEFORE-USED") ⇒  NEVER-BEFORE-USED, NIL
 (intern "NEVER-BEFORE-USED") ⇒  NEVER-BEFORE-USED, :INTERNAL

 (find-symbol "CAR" 'common-lisp) ⇒  CAR, :EXTERNAL
 (find-symbol "NIL" 'common-lisp-user) ⇒  NIL, :INHERITED
 (find-symbol "NIL" 'common-lisp) ⇒  NIL, :EXTERNAL
 (find-symbol "NIL" (prog1 (make-package "JUST-TESTING" :use '())
                           (intern "NIL" "JUST-TESTING")))
⇒  JUST-TESTING::NIL, :INTERNAL
 (export 'just-testing::nil 'just-testing)
 (find-symbol "NIL" 'just-testing) ⇒  JUST-TESTING:NIL, :EXTERNAL
 (find-symbol "NIL" "KEYWORD")
⇒  NIL, NIL
OR⇒ :NIL, :EXTERNAL
