> ArrayConstructorExpression.evaluate() currently deserializes into object form
> all array elements only to serialize them back again as bytes. Instead, just
> use a TrustedByteArrayOuputStream (initially sized based on the number of
> child elements) to serialize the data into. If variable length, track the
> offset information as the data is written.
> Second, we should put the header information (offsets, length, and version)
> at the end of the array instead of the start. This will make it possible to
> compare arrays against each other in their byte form.
