Far from it.  You need at least one or two years studying lisp before
getting close.

You have a lot of non-conforming code (starting with your defpackage
form).

FILE-WRITE-DATE could return nil while the file is still loadable.
If you don't want to modify the package if the file can't be openned,
you can open it with WITH-OPEN-FILE, and pass the file-stream to LOAD.


cl-user> (load "mb.lisp")
;Compiler warnings for "/home/pjb/mb.lisp" :
;   In homeless-symbol-reader: Variable stream not ignored.
#P"/home/pjb/mb.lisp"
cl-user> (use-package :mb)
t
cl-user> (with-package (cl-user)
           (let ((#1=#:hello 'world))
             (print (list #1# #1#))))
