This appears to be the result of a bit of cut and paste from the at and at_c implementations, which
also have the redundant typedef. The get implementations should be calling at_c directly, rather than
implementing more tag_dispatching to the at_impl type themselves. I've tidied things up, removing the
redundant typedefs in both get and at, and modifying get to call at_c directly.

Thanks for pointing this one out.
