     * In addition to producing a compiled field, we also support consuming
     * a compiled field back into our internal representation for further
     * processing (for example, this could be useful for static analysis).
     * This is important---the compiled datum should be treated as opaque,
     * so the only way to make practical use of it is to decompse it back
     * into its internal representation.
     *
     * Note that there is no way to actually retrieve the internal datum
     * other than compiling it; however, beacuse the compiled datum is to be
     * treated as opaque, there is also no way to inspect that value after
     * parsing it.
     *
     * Once composing a ProtoField, it is not possible to retrieve and
     * analyze the raw value that composed it. In practice, this is not
     * necessary.
