What is the purpose of these (void)?

If you are getting an unreferenced variable warning from the compiler, I would
just delete the names from the argument list above.

This was more just preemptive to avoid a compiler warning.  Removed and will see
if Try returns any errors.

I don't think we generate such warnings. Just remove these.
