Description
The following error comes up when running CPython.test_memoryio.test_instance_dict_leak:
TypeError: The result type 'System.Int32' of the dynamic binding produced by the object with type 'IronPython.Modules.PythonIOModule+StringIO' for the binder 'Python SetMember foo' is not compatible with the result type 'System.Object' expected by the call site.

Research direction
Start by reproducing the failure in CPython.test_memoryio.test_instance_dict_leak and inspect the dynamic binding path involved for _io.BytesIO and _io.StringIO. Done means the test no longer raises the reported TypeError and the affected member assignment produces a compatible result type.
