Remove "__type" in favor of "name" in Exceptions

Is your feature request related to a problem? Please describe.
We now include __type and name on every structure. The 'name' was only being added on exceptions, but that isn't the case. We need to either only add 'name' to exceptions and leave __type how it is, or we need to remove __type altogether.
