### 4.2.2 bigintmat expressions

A bigintmat expression is:

1. an identifier of type bigintmat
2. a function returning bigintmat
3. a bigintmat operation involving (big-)ints and int operations (`+`, `-`, `*`)
4. an expression involving bigintmats and the operations (`+`, `-`, `*`)
5. a type cast to bigintmat (see bigintmat type cast)

Example:

      bigintmat m1[2][2]=1, 2, 6, 3;
      m1*3;
    ==>  3,6,
    ==> 18,9
      intmat im[3][2] = intmat(m1*3);
      bigintmat m2 = bigintmat(im); // cast intmat im to bigintmat
      m2;
    ==>  3,6,
    ==> 18,9
      m2*m1+m2;
    ==> 42,30,
    ==> 90,72
      _+4;
    ==> 46,34,
    ==> 94,76
