Comment (by cheuberg):
Apart from that, I made three more changes:
*

4d160d7] Trac #17221: move parsing of equation to a different method
transducers.Recursions had two major parts: parsing the symbolic
equations and actual construction of the transducer. These first part
has now been refactored into a new method.

446f8f4] Trac #17221: Allow alternative input format (rules)
Allow to enter the recursions in the form of rules as they are stored
internally. In that case, no symbolic function and no variable are
needed,
so the order of the parameters has been changed.
