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.
