> {quote}Hmm, it looks like the implementation could be more optimized. When
> appending multiple scalars (or multiple times the same scalars), the required
> space could be reserved. Also, at least for primitive types, I would expect
> appending multiple scalars to be much more streamlined than this.
> (it looks like such optimizations could be crafted more easily if
> {{AppendScalar}} was a bunch of virtual methods?)

> Also, dictionary scalars aren't supported. You could imagine both appending a
> dictionary scalar to a regular builder (decoding the value) and appending a
> dictionary or regular scalar to a dictionary builder (encoding the value as
> necessary).
