Ah, yeah, so thinking about this: any value whose accessors
depend on the size of the value [that is stored within the
value itself] isn't going to work. The "sub-values" (e.g.
the individual records) inside a single [Flat_array] value
don't have the usual size field in the header. Strings are
an example that will hit this problematic case.
