State-Changed-Why:
    Very interesting. Indeed, this
        (int &)3 = 2;
    compiles into this:
       	movl $3,-4(%ebp)
    	leal -4(%ebp),%edx
    	movl $2,(%edx)
    (Sure, after all, the code said: "take the address of the
    3, and write a 2 into that place").
    
    
    As an aside, from hearsay, some Fortran compilers allowed
    you to do this:
          subroutine f(i)
          i = 2
          end
    
          subroutine g
          call f(1)
          write (*) 1
          end
    
    If you were unlucky, and the compiler chose to use the same
    address for the two ones in g(), then you'd get a "2" onto
    your screen, though you wrote "write (*) 1".
