MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          tail(cons(X,XS)) -> XS
          zeros() -> cons(0(),zeros())
      - Signature:
          {tail/1,zeros/0} / {0/0,cons/2}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {tail,zeros} and constructors {0,cons}
  + Applied Processor:
      NaturalPI {shape = Mixed 3, restrict = NoRestrict, uargs = UArgs, urules = URules, selector = Nothing}
  + Details:
