(eval form) normally evaluates "form" in a null lexical scope.

How can I do an "eval" within the lexical scope from which the "eval" is called?
     e.g. I would like to do the following:

       (defun test ()
	 (let ((form)
	       (a ..)
	       (b ..)
	       (c ..)
	       (any-number-of-variables 
		    ....
		       ))
           ... 
	   ...
	   (eval form)))       ; where "form" may reference any of the variables
                               ;  in the lexical scope when eval is called.
	 
Suppose that you do not even know the names of all the local variables
	that "form" may reference.

It seems to me that you have to use *evalhook* and evalhook, but I can't seem to get them to
  work for me for any general "form".
