https://bugs.ruby-lang.org/issues/5759
There is no to_ary function for Enum::EnumValue, but it does respond to to_ary calls with method_missing.
For example, [STATUSES.some_enum_status].flatten will fail on undefined method 'to_ary'.
So this is meant to indicate rails to not use to_ary on this object.

Was tested on
Rails 4.2.11 + Ruby 2.3.8

@odedniv is it possible to release a version with this fix?

Thanks for the PR! 2 questions:

  1. Can respond_to_missing? be implemented in a more general way? Should it be a mirror of method_missing (i.e return true for anything that would be caught there)?
  2. Can you add tests? It should reflect the implementation, so perhaps hold on that until we have question 1 agreed upon.

Will definitely release a version once this PR is merged.

@odedniv Yeah, we don't have capacity to do it now so we will add the change to our Simplee repo for now.
When il'l have some time I will add the tests.
