It comes from C. This was done in C so that addresses of
struct
instances will always be unique.
Why is that important, and why does D need it?
In C, this might make some sense, however empty structs are
much more
useful in D, e.g. for metaprogramming.
struct Z {};
Z a, b;
assert(&a != &b);
Yes, but why is this important? If you declare Z as "alias int[0]
Z", the assert passes, so why is this property needed for structs
but not static arrays?
