Jerry Leichter's comment about being able to tell by looking at reference
to a name whether its value may be implicitly or directly changed seems to
have a hole in it.  If I pass an array to a function by specifying the array
name, a pointer to the array is passed, thus making it possible for the
function to change the contents of the array.  However, I have to remember
that the object was declared as an array to realize this.  It isn't
explicit in the call syntax.
