coupled with wholesale deletions of functions that previously had
identical bodies. Nice.
[I suspect there might be ways to trim a LOT more code size, by
rewriting a generic marshaller helper that is passed a varargs or
array-of-struct list of operations to perform in order to visit an
arbitrary object, then having each command's marshaller generated with
the appropriate list of arguments for the generic helpers rather than
the current approach of calling out to one marshaller helper per type -
but exploring ideas like that is work for another series]
