Wrong error when importing non existing subtype

> Main.hx
```haxe
import Types.Baz;
```

> Types.hx
```haxe
enum Bar {}
```

```
$ haxe Main
Main.hx:1: characters 8-13 : Module Types does not define type Types
```

Here it's ok that `Types.hx` does not define type `Types`, but the error should complain about `Bar` vs `Baz` instead.
