Well I tried the shadowing import, compiles fine, but when attempting to
load that fas, it will throw redefinition error
(defpackage :test)
(in-package :test)
(shadowing-import 'open)
(defun open (filespec &key direction element-type if-exists
if-does-not-exist
external-format)
(print "test")
(cl::open filespec :direction direction :element-type element-type
:if-exists if-exists :if-does-not-exist if-does-not-exist
:external-format external-format))
