the nameref variable is referenced, assigned to, unset, or has its
attributes modified (other than the _n_a_m_e_r_e_f attribute itself), the
operation is actually performed on the variable specified by the

functions to refer to a variable whose name is passed as an argument to

values by subsequent assignment statements or unset.
