Just a small side-issue...  Suppose we have a super.new
that expects one int argument, how about these two cases?

case 1: conditional call
~~~~~~~~~~~~~~~~~~~~~~~~

function new(int A);
  if (A!=0)
    super.new(A);
  else
    super.new(-1);
...

case 2: call with function or expression in arguments
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

function new (int A);
  super.new(A-1);
  // or even...
  // super.new(some_function(A));

At least one simulator let me get away with case 1 the
last time I tried it.  I haven't checked case 2.
Clearly it involves something being executed before
super.new, and yet it looks fairly sensible (especially
if some_function is a static method of the class).
