It sounds OK, as long as there's nothing in Thoth that's going to be
masked by what's already in Object. For example, if there's a
Thoth::String, you won't see it:

irb(main):001:0> module M; String=1; end
=> 1
irb(main):002:0> include M
=> Object
irb(main):003:0> String
=> String

as opposed to:

irb(main):004:0> irb M
irb#1(M):001:0> String
=> 1
