Why is this allowed

struct EntityDef
{
    struct
    {
        int hp;
    }
}

But not this fucking thing?

struct EntityDef
{
    struct
    {
        int hp;
    } stats;
}

Let me name my shit

No, i don't want to do:

struct EntityDef
{
    struct Stats
    {
        int hp;
    } Stats stats;
}

Repeating the same name 3 times, i should go back to the stone age too no?

C and all other C like languages allow me to be concise

Why is it a D thing to be backward?

In the coding scheme, fields/members/methods may be at the beginning, middle, or end of the structure, or may not be identifiers to the right of the anonymous structs. In structures, a lot (I wish it was in bitfield) has been taken from C. Especially not using typedef and not having extra semicolons make D stand out even with these. As for anonymous structures, they have to be like this in order to be used with unions.

I think everything is as it should be, and even more: Please include the relevant comment line (the // characters next to the anonymous struct) in the code and be amazed by the change :)

struct Foo
{
    int bar;

    //struct {/*
    Baz baz;
    struct Baz
    {
        auto opAssign(int value)
          => baz = value;//*/
        int baz;
    }
}

void main()
{
    Foo foo;
    foo.bar = 7;
    foo.baz = 42;
    
    imported!"std.stdio".writeln(foo); /*
    with opAssign()      Anonymous
    Foo(7, Baz(42))  or  Foo(7, 42)    */
}

Thank you to the creators and maintainers of the D.

It’s the semicolon. As soon as the closing brace, the declaration is over. You would have to invent new syntax.

I literally don't understand what your code does

I'm not sure this is related to my suggestion

There is no new syntax to invent

instead of writing this error:

onlineapp.d(8): Error: no identifier for declarator `stats`

you generate a random identifier and assign it

    extern(D) static Identifier generateAnonymousId(const(char)[] name)

I'm very far from being bright, but i know simple logic

Maybe type tuple syntax will support this:

struct EntityDef
{
    (int hp) stats;
}

EntityDef ed;
int x = ed.stats.hp;
