Description basile-z 2021-10-02 11:51:57 UTC 
To https://dlang.org/spec/module.html#MixinDeclaration, add two paragraphs:

"The content of a mixin cannot be forward referenced by other DeclDefs of the same scope because it is not yet pulled in the AST"

```
class B : A {}
mixin ("class A {}");
```

"forward references may only work in function bodies because they are processed after the declarations"

```
void v()
{
    class B : A {}
}
mixin ("class A {}");
```
