Array with empty/absent items generates untyped List

[oefe]

I'm not sure whether this would be considered a bug, but an OpenAPI array with empty items (or no items field at all), like this:

          "contents": {
            "type": "array",
            "items": { },
            "nullable": true
          }

Generates a list without type arguments:

    contents: Optional[List] = None

While this is syntactically correct, type checkers may warn about this.
For example Pylance will issue reportMissingTypeArgument:

Expected type arguments for generic class "list"

I would therefore expect a type argument:

    contents: Optional[List[Any]] = None

Good news!

• Related to schema -> msgspec.Struct / typing.TypedDict converts List[Any] to List #2325
• Fixed by Fix empty array items to generate List[Any] instead of bare List #2584

Closing 🙂
