* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          int(0(),0()) -> .(0(),nil())
          int(0(),s(y)) -> .(0(),int(s(0()),s(y)))
          int(s(x),0()) -> nil()
          int(s(x),s(y)) -> int_list(int(x,y))
          int_list(.(x,y)) -> .(s(x),int_list(y))
          int_list(nil()) -> nil()
      - Signature:
          {int/2,int_list/1} / {./2,0/0,nil/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {int,int_list} and constructors {.,0,nil,s}
