It’s an internal class, the object is tucked into the metadata to exchange
info between event handlers. The variable starts with ‘_’ so is clearly
meant to be internal. That said, there’s nothing preventing use of any
arbitrary type in a metadata value, so if code is expecting particular
types, it should be fixed to exclude types it doesn’t understand, or just
str() the values.
