I looked at this and I understand what is going on. We need the code up to
here. We'll never get this far if we have the wrong number of initializers
because this happens after initializer flattening. We should add an assert
`assert(NumEltsInit != MaxElts)`, and drop the rest of the function because
that's unreachable.
