| ### 4.9.3 intvec operations `+` addition with intvec or int (component-wise) `-` negation or subtraction with intvec or int (component-wise) `*` multiplication with int (component-wise) `/`, `div` division by int (component-wise) `%, mod` modulo (component-wise) `<>`, `==`, `<=`, `>=`, `>`, `<` comparison (done lexicographically, different length will be filled with 0 at th right) intvec_expression `[` int_expression `]` is an element of the intvec; the first element has index one. Example:
      intvec iv =  1,3,5,7,8;
      iv+1;               // add 1 to each entry
    ==> 2,4,6,8,9
      iv*2;
    ==> 2,6,10,14,16
      iv;
    ==> 1,3,5,7,8
      iv-10;
    ==> -9,-7,-5,-3,-2
      iv=iv,0;
      iv;
    ==> 1,3,5,7,8,0
      iv div 2;
    ==> 0,1,2,3,4,0
      iv+iv;              // component-wise addition
    ==> 2,6,10,14,16,0
      iv[size(iv)-1];     // last-1 entry
    ==> 8
      intvec iw=2,3,4,0;
      iv==iw;             // lexicographic comparison
    ==> 0
      iv < iw;
    ==> 1
      iv != iw;
    ==> 1
      iv[2];
    ==> 3
      iw = 4,1,2;
      iv[iw];
    ==> 7 1 3
