The difference is purely syntactical. Calls to overloaded functions look,
well, like function calls. Calls to polymorphic functions require a dot or
'->' somewhere. Really, that's the only difference. Artificial semantic
restrictions placed by certain languages aside, you can always move the
identifier or address-expression from the left of the dot into the
parenthasis as the first argument to generate an equivelent overloaded
Next question: is there a difference between the functional language notion
of a polymorphic type and inheritance (other than functional language type
hierarchies being limited to one level)?
