     Scheme is call-by-value; arguments to procedures are copied into the
    parameters in the procedure's environment. As I understand it, even when
    the argument is a reference - such as with a list - a full copy of the
    argument is made local to the procedure.
 If by "a full copy" you mean that a list passed to a procedure will be
copied, then you are mistaken.
