    ECMA Section:       15.5.1 The String Constructor called as a Function
			15.5.1.1 String(value)
			15.5.1.2 String()

    Description:
	When String is called as a function rather than as
			a constructor, it performs a type conversion.
			- String(value) returns a string value (not a String
			object) computed by ToString(value)
			- String() returns the empty string ""
