MAYBE

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict Trs:
  { active(eq(X, Y)) -> mark(false())
  , active(eq(0(), 0())) -> mark(true())
  , active(eq(s(X), s(Y))) -> mark(eq(X, Y))
  , active(inf(X)) -> mark(cons(X, inf(s(X))))
  , active(inf(X)) -> inf(active(X))
  , active(take(X1, X2)) -> take(X1, active(X2))
  , active(take(X1, X2)) -> take(active(X1), X2)
  , active(take(0(), X)) -> mark(nil())
  , active(take(s(X), cons(Y, L))) -> mark(cons(Y, take(X, L)))
  , active(length(X)) -> length(active(X))
  , active(length(cons(X, L))) -> mark(s(length(L)))
  , active(length(nil())) -> mark(0())
  , eq(ok(X1), ok(X2)) -> ok(eq(X1, X2))
  , s(ok(X)) -> ok(s(X))
  , inf(mark(X)) -> mark(inf(X))
  , inf(ok(X)) -> ok(inf(X))
  , cons(ok(X1), ok(X2)) -> ok(cons(X1, X2))
  , take(X1, mark(X2)) -> mark(take(X1, X2))
  , take(mark(X1), X2) -> mark(take(X1, X2))
  , take(ok(X1), ok(X2)) -> ok(take(X1, X2))
  , length(mark(X)) -> mark(length(X))
  , length(ok(X)) -> ok(length(X))
  , proper(eq(X1, X2)) -> eq(proper(X1), proper(X2))
  , proper(0()) -> ok(0())
  , proper(true()) -> ok(true())
  , proper(s(X)) -> s(proper(X))
  , proper(false()) -> ok(false())
  , proper(inf(X)) -> inf(proper(X))

  , proper(length(X)) -> length(proper(X))
  , top(mark(X)) -> top(proper(X))
