[Twisted-Python] automat question

[Glyph]

Automat is designed to make this sort of thing intentionally annoying, as you have discovered:).  

The idea is that if you want to know this sort of internal state, it’s for a specific reason. That's not a blanket "No" — see for example how automat deals with serialization — but each such interface should be minimal and thoughtfully designed. Otherwise a state machine library just becomes a bunch of complex infrastructure around making an arbitrary series of function calls, and loses all of its helpful formalisms.  

So probably we do need to make a change to automat if you really need to do this, but first it's important to know what your use-case is. In a lot of cases the answer is "just make an output. Stop trying to make the application see into the guts of the framework." But without knowing it’s impossible to say!
