 1****** Warning: Actually, `Void' has no accurate type. Keep in
 2mind that `Void' is just a way to denote the default value for
 3a type or to denote the lack of an object. One can use `Void'
 4as the right-hand-side of an assignment or to replace some actual
 5argument. (See "http://wiki.liberty-eiffel.org/index.php/Void"
 6for details.) At time being, the type ANY will be used for this
 7occurrence `Void'. Please update your code with a more accurate
 8expression, may be by adding an extra non-initialized local variable.

14****** Warning: Using `Void' as an item of a manifest TUPLE is
15not good practice because `Void' has no accurate type. You can
16work around by using an extra non-initialized local variable of
17some accurate type. Another work around is to use an explicit
18creation of the TUPLE. As an example `create {TUPLE[STRING,ANY]}.make_2(Void,Void)'
19can be used to create a TUPLE[STRING,ANY] with default values.
