Questions about using copyable_any

[lumos42]

Seems like we can't have copyable_any::Any as a param to an entry function. I get the error:

type `copyable_any::Any` is not supported as a transaction parameter type

i want to receive dynamic data in a transaction, which could be either of 2 structs. I can't receive bytes(vector<u8>) either cuz there's no way to pack bytes into Any type. What's the right way to do this?

Found a way to make this work by having a generic entry function, and then packing it into Any in the entry function
