MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          from(X) -> cons(X,from(s(X)))
          length(cons(X,Y)) -> s(length1(Y))
          length(nil()) -> 0()
          length1(X) -> length(X)
      - Signature:
          {from/1,length/1,length1/1} / {0/0,cons/2,nil/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {from,length,length1} and constructors {0,cons,nil,s}
  + Applied Processor:
      NaturalPI {shape = Mixed 3, restrict = NoRestrict, uargs = UArgs, urules = URules, selector = Nothing}
