Hierarchical state machines with :gen_statem and change_callback_module

[icecap]

Can change_callback_module action be used to run :gen_statem in series to create hierarchical state machines?

I don’t know :gen_statem but hierarchical state machines bring some non-trivial stuff, so I doubt it.
A very good resource on the topic is chapter four of Pracical UML Statecharts in C/C++.
