+/**
+ * The primitive types can give some headaches.  You almost never can say
+ * if a local variable is of type int, char, short etc. <p>
+ *
+ * Most times this doesn't matter this much, but with int and character's
+ * this can get ugly. <p>
+ *
+ * The solution is to give every variable a hint, which type it probably is.
+ * The hint reset, when the type is not possible.  For integer types we try
+ * to set it to the smallest explicitly assigned type. <p>
+ *
+ * Some operators will propagate this hint.<p>
