1) removed many debug prints
2) solved a bug in automation (we had forgotten to saturate clauses in
forward_infer_step, a mistake that prevented equations from being

status containing the correct environment, which can't be guessed
inside compare (enabling alpha_eq results in the automation
sporadically failing).
