My usecase is pretty trivial: A linked list. This is often implemented
as a "single" sentinel that serves as both pre-head/post-tail. When the
list is empty, the sentinel simply points to itself.
You could use internal pointers for this case as long as:
a) The struct will never get copied and/or moved. No pass by value, only
pointers.
b) It's out of GC control and in particular GC-allocated built-in arrays.
This means you don't have that much of choice beyond things like:
MyObject* node = (MyObject*)malloc(MyObject.sizeof);
s/(MyObject*)/cast(MyObject*)/
Too much of C on me lately ;)
