I'd expect that the `isInstanceOf` would be true instead of false here.
Commenting out the public import changes the output of `fullyQualifiedName`. I can kind of see why this happens, but it's kind of annoying when things like `isInstanceOf` silently fail due to this.
For context: I found this after getting a compiler error after stitching a bunch of D files together, which is why there's a mix of a public import and local import in the same file.
Part of me feels like it's a bug since if the alias `T` is using one "version" (for lack of a better word) of `Nullable`, then surely that same "version" would be given to `isInstanceOf`?
It can get a bit more interesting as well: https://run.dlang.io/is/n5jzJs
