Comment:

 Hi Andrey,

 I got two questions:

  - are those objects instance of a subclass of {{{Element}}}, do they have
 a parent ?
  - are they immutable as {{{tuples}}} ?

 If so, Its fairly possible that we would use them to represent element of
 cartesian products. They are currently represented as tuple so they don't
 have a parent.
