## Starred bases
These are currently not supported, but ideally we would support them in some limited situations.
```py
from ty_extensions import reveal_mro
class A: ...
class B: ...
class C: ...

class Foo(*bases): ...
# revealed: (<class 'Foo'>, @Todo(Starred expressions in class bases), <class 'object'>)
