+    This is basically the inverse of a multi-part form parser, which can additionally
+    handle nested entries.
+
+    The main use-case for this is constructing requests in Python that emulate
+    a multipart FormData payload that would normally be sent by the frontend.
+
+    Nested entries get flattened / hoisted, so that the final dict is a flat
+    key-value map, with bracket notation used for nested entries. List items are
+    also hoisted up, with indices put within leading brackets.
+
+    Warning: values are not stringified (but would be in a true multipart payload)
+
+    @example
+    ```
+    nested_dict = {"a": 1, "multi": [{"id": "abc"}, {"id": "123"}]}
+    print(object_to_multipart_dict(nested_dict))
+    # > {'a': 1, 'multi[0][id]': 'abc', 'multi[1][id]': '123'}
+    ```
