will this no longer work now?

It would have to be small d dynamic. This is another editor auto-change. I think
Object will work also work. It seems to make no difference, I suspect the
explicit Dynamic was to prevent the editor from showing spurious warnings. This
is just an internal helper class, so removing the declaration altogether to be
consistent with the others. I don't get any warnings, and it all runs fine.
