It would be nice if we could save models in a binary format that would be faster to read etc.

The model could be saved after preinitialize():

PubSubs connected, along with any other topological transformations
Types checked
Relation widths inferred

In some ways, this would be like byte code for the model. The model could be opened and run and if there were no changes (or only "safe" changes) then various steps would not need to occur.

Being able to save models in binary format would greatly improve startup performance.

One idea would be to try to use serialization, though getting all the caches set up properly could be complex.
