I presume its because you can have

void foo (int &i) { i = 666 ; }

which is meaningless for a call of foo(5).

Actually, there used to be a Fortran compiler for the IBM/360s (Watfor?)
where you could do the equivalent, after which 5 became 666 under certain 
circumstances. It was a great one for fooling the duty programming advisor :))
