### 4.9.1 list declarations

Syntax:
  `list` name `=` expression_list`;`
  `list` name `=` list_expression`;`

Purpose:
  defines a list (of objects of possibly different types).

Default:
  empty list

Example:

        list l=1,"str";
        l[1];
      ==> 1
        l[2];
      ==> str
        ring r;
        listvar(r);
      ==> // r                              [0]  *ring
        ideal i = x^2, y^2 + z^3;
        l[3] = i;
        l;
      ==> [1]:
      ==>    1
      ==> [2]:
      ==>    str
      ==> [3]:
      ==>    _[1]=x2
      ==>    _[2]=z3+y2
        listvar(r);     // the list l belongs now to the ring r
      ==> // r                              [0]  *ring
      ==> // l                              [0]  list, size: 3
      ==> // i                              [0]  ideal, 2 generator(s)
