I have a 3rd party Ruby library that, prior to version 7.1, was able to call the subject method with a nil argument and receive back the results of Selectable#reset_strategies!.  Now, Selectable#where raises an exception on a nil argument, which causes my application to crash.

I worked around my problem with a kludge that adds the following at the beginning of the version 7.1 Selectable#where function:

if criteria == [nil]
    return self.reset_strategies!
end

Now my application runs fine.  However, since I don't have a deep knowledge of Mongoid and ActiveRecord internals, I have no idea if this is reasonable or not.

In any case, if you can come up with a better solution, or some guidance about how the 3rd party vendor routine can get the desired result without calling Selectable#where(nil), I would appreciate it.
