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