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