It looks good. It's not a strongly typed code (because states are 
just chars), and it's not much flexible because UTM is not 
templated on Symbol and State, but for this task it's OK.

Some small changes:

Before putting it in Rosettacode the UTM constructor needs a 
pre-condition that verifies the full correctness of all its 
inputs. Then do you want to put it in Rosettacode yourself?
