This one is related to PR 46262: Both contain polymorphic type-bound operator
calls with "non-trivial" operands. In the example here one might still just
"optimize away" the parenthesis, but in more general cases like

u = (u*2.)*3.

one needs to insert a temporary (ditto for PR42626), so that this line is
translated into something like:

{
  class$field tmp;

  tmp = u.$vptr->multiply_real (u,2.);

  u = tmp.$vptr->multiply_real (tmp,3.);
}

This does not work yet.
