 C<Nil>, when assigned, evaporates into the type object of the type of the

 It is for this reason that assigning an untyped container as C<Nil> will result
 in an C<(Any)> object.

 This is because an untyped container is C<Any> until proven otherwise, and
 the C<Nil> evaporates.
 
 If you are looking for a variable which transforms objects into type objects
 when said variable appears on the RHS, you can type the container as C<Nil>.
