Well, strong typing is unrelated to type conversions, so the sentence above
is nonsense. Actually, *logically* (meaning semantically) unrelated types
can be mixed without any conversions:

   int ArrayIndex;
   int EmployeeID;

   Employee_ID = Arraj_Index:

The question is whether a strongly typed language is designed in order to
support and encourage mapping logically unrelated entities onto physically
unrelated types or not. Ada more or less is, C++ more or less is not.
