T: Type "T" has multiple definitions

you get the error `T: Type "T" has multiple definitions` in this example:

```
import { T as OtherT } from './other.js';

export type T = OtherT & { a: string };
```

i think the problem is that the generator is attempting the name the imported type as T, which clashes with the type defined locally. would it be possible to name the type with the alias `OtherT` to prevent conflicts?
