I believe destructors are not run when you throw inside a
constructor. So plan to deallocate if the ctor throws:
a = A(var + 1);
scope(failure) destroy(a);
The spec says [1], that the first write to a field in a class's
constructor is a construction, not an assignment. I assume this
applies to structs as well. If so, this implies that the compiler
already knows at each point which fields are already constructed.
Why doesn't it automatically insert appropriate destructor calls
then?
