Behrens' Bayesian Learner Model : How to share parameters between steps?

The only reason I am not to do this is that it may be an impolite behavior that shares Stan code in PyMC3 community.

That’s not a thing to worry about. There is actually a lot of cross-talk between PyMC3 and STAN (mostly we stealing ideas from them)
