Perhaps the fact that I used Python syntax was too ambiguous <wink> but I
was talking about Python. However, the same applies to Java, if you
substitute an object for the primitive value:

    Integer x = new Integer(23);

According to the Java philosophy, the value of x is not the object
Integer(23) like any sane person would expect, but some invisible and
unknown reference to that object.

Clear now?
