PR #2833 introduced more flexible handling for the type of the default parameter, but the extra type variable caused some issues. Add another overload for the case where there is no default param. This is I think related to the issues we have had with `get` recently?

Won't mypy still complain about calls without default= because this overload can still be called that way? (I.e. why not make default mandatory in this overload?

mypy will take the first overload, I think, so the change did fix the issue, but I will make it mandatory
