My "tuple type" is an actual tuple. While I could create custom comparison
operator for e.g. `Tuple{Int, Int, AbstractString}`, this would be
unorthodox, as this comparison operator would be globally visible. This
could break many things, such as e.g. dictionaries that hold tuples of
arbitrary type.
