Hello,
how can calling method on local struct throw "null this"?
struct is initialized by .init and have default values.


struct Foo {
Bar bar;

    static struct Bar {
        float x, y, z;
    }

Bar getBar() {
return bar;
}

}


then
Foo foo = Foo.init;
auto b = foo.getBar(); // throw "null this"

cast(ulong)&foo but is not null.

It won't work just in special cases what I cannot reproduce easily.

Well that code definitely works fine as is.
Perhaps remove that static, it makes me a little queasy just looking at it.

Also no need to set foo to Foo.init, it already is that value.

I had
auto ref getBar() inout {
    return bar;
}

in which was problem. When I separated it into 2 funcs get/set it works fine.
