Come up with a plan for 'redirect'.
probes should never modify the state of the world. Currently, there is no protection to guarantee this, except for something in lpxclient where it does a snapshot and rollback before and after the probe. We should come up with a more comprehensive mechanism.
Questionable Design Choices
When we delete a tangible, we currently leave the LUA_TT_TANGIBLE flag on the table, and we leave the metatable in place with the tangible ID in it. Is this the right thing to do? Should we turn it into a truly blank normal table?
Hard Problems without Solutions
Using Multi-Core CPUs: We want to do difference transmission in parallel (one thread per connected client). This may be possible because each synchronous model is a separate lua interpreter. However, the master world model is shared. It may be possible to access it in a read-only manner in multiple threads.
Nonsortable Keys: what to do about table keys that are other tables, closures, or coroutines?
Collision Detection: In the old engine, people could walk through walls. I don't know if that is okay in 2020. But the separation of world-model and graphics engine makes this hard.
Dealing with Infinite Loops: if the script goes into an infinite loop, there's no easy way to deal with that. The lua interpreter does have hooks where you theoretically could count cycles.
Module-Level Locals: module-level locals are useful to store constants. However, when they're used as variables, they create pseudoglobal state that gets reset every time you edit a source file, and which is unfindable by the difference transmitter.
