I cannot tell if you are serious in your question seeing that you
required `cl-lib' in your own implementation.  Thus, I presume that you
were at least somewhat familiar with the Common Lisp emulation package,
and so I am puzzled how you missed `defun*'.

In any case, C-h f tells me, at least, that

  defun* is an alias for `cl-defun' in `cl.el'.

  (defun* NAME ARGLIST [DOCSTRING] BODY...)

  Define NAME as a function.
  Like normal `defun', except ARGLIST allows full Common Lisp
  conventions, and BODY is implicitly surrounded by (cl-block NAME ...).

I made the mistake of using the alias `defun*' instead of the namespace
clean `cl-defun', simply because I have been using the star suffixed
form since before "Stefan Monnier added the file ‘cl-lib.el’ and
rationalized the namespace for Emacs 24.3." (from the GNU Emacs Common
Lisp Emulation Info manual), but that does not alter my basic point.  If
you have `cl-lib', you should have the rest too.
