Updating the automatons counts as an object modification, so yes it
could.  Eventually, as the automatons are fleshed out and most calls
no longer result in an update, the rollbacks would desist.

If initial rollbacks are an issue, you could create a new parser object
each time, have multiple parser objects, or train the parser with sample
input in the beginning.
