how do we handle traits in global state without an explosion of type declarations?

[thedavidmeister]

i had this problem while trying to put a chain and/or hash table in the agent state

because we want to implement our memory/file/db storage of data as a trait, AgentState complains about type declarations unless we do something like box the trait

when we box the trait, it's much harder to do things like clone/reference/etc.

when we put the type declarations on AgentState, then it complains about type declarations on State, which then complains about type declarations on Persister, which then complains about a half dozen other type declarations...

i assume that we'll have the same problem with any trait, e.g. if we want the network interface to support bluetooth/wifi/etc. and then try to put it in the global state, we will suddenly have to start declaring the network type everywhere too

in the short term i commented out the usage of source chain straight from the agent state

I appologize if my suggestion has already been done before, but would bounded generics help?
