Just out of curiosity, what is the point of the following?

As far as I can tell, the anonymous structure does nothing.
How is it different from
struct a{
int x;
int y;
int z;
}
IIRC D doesn't allow anonymous structures.
It does, it compiles...
Accessing x,y,z on the first one with the anonymous struct is the
same as accessing it on the second without the anonymous
struct... Seems to make no difference that it is there, which is
why I am asking.
Also is there a way to have a named substructure, not a nested
structure but something to just add an additional name, maybe
something like
struct a{
struct{
int x;
int y;
int z;
} b;
}
Try adding static:
struct a
{
static struct b
{
}
}
Does not seem to be what I mean, a static nested struct is just a
nested struct without access to the enclosing structure's
members. What I meant was a struct to just add a namespace of
sorts to the struct so that the substructure members would have
to be accessed with a longer more qualified name. Something like
struct a{
int x;
sub_struct b{
int y;
}
}
a v;
v.x = 3;
v.b.y = 7;
// v.y = 7; // does not work
