Therefore, we don’t recommend building your business Furthermore, many fundamental resources like network sockets and files are, implicitly, managed by state machines, in that certain operations are only valid on resources in certain states, and those operations arguments are used consistently. However, statically checking that operations are performed only on resources in an appropriate state is not well supported by mainstream type systems.
