Struct have that except for default constructor. In D, currently default
constructors cannot execute code. This is a limitation that we might
need to address, although it has some advantages.
There are things that copy constructors can do that the post-blit
operator can't do.
Yes, mostly wrong things. I think it would be a huge loss if D copied
C++'s model.
This means that structs cannot hold on external resources, ever:
struct RAII {...}
var a = RAII("foo");
var b = RAII("bar");
a = b; // you just leaked a and corrupted b
You may be making a confusion between assignment and copy construction.
