"can't do" is not the same as "is not a syntactical built-in". Of course Haskell can represent bounded integers:

Also, Pascal's ranged integers are only for literals; the are not thoroughly enforced by the compiler. They are trivial to circumvent:

    var
      y,z: 5..10;

    Begin   
      Read(y);   Writeln(y);  // 60 works here
      y := 10;
      z := 2*y;  Writeln(z);
