• get_symbolic_from_meta() enforces that meta is an instance of MetaInfo (via an isinstance check), which may be too restrictive when NullInfo (a valid MetaInfoBase subclass) is passed for optional tensor outputs. Consider updating the type check or handling for NullInfo to avoid unexpected errors.

• Changing the return value from a py::list to a std::vectorpir::Value might affect downstream code that expects a Python list interface. Ensure that consumers of this API are updated to handle the new return type.

• The branch for handling uninitialized tensors currently returns an empty guard list with a TODO comment. To ensure reliable guard checking, consider implementing a proper guard or adding clear documentation on how this case should be handled in production.
