4.5.3 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)

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
