           Summary: Import order emits "Error: no size because of forward
                    references"

ldc2 1.30.0-beta1 which is dmd v2.100.0. Windows MSVC 64bit.

Depending on import order I am getting a lot of: "Error: no size because of forward references".

Works:

```d
import sidero.base.text.unicode.builder;
import sidero.base.text.unicode.readonly;
```

Doesn't:

```d
import sidero.base.text.unicode.readonly;
import sidero.base.text.unicode.builder;
```

Both modules in question import each other but neither depends on the other for their size of any type (but are used for method parameters).

I am using a lot of scope and scope + ref in parameters, so this could be related to https://issues.dlang.org/show_bug.cgi?id=21667
