> The whole thing is quite R6RS-ish anyway, modelled after R6RS's
enumeration types. In R7RS, I would expect `'big` and `'little` as in
classical Scheme.

Yes, which is why I added `endianness?` (R6RS should've exposed an
endianness enum set so that one could use the (rnrs enums (6))
operations to implement `endianness?`).

However, `endianness` is still there, and it is not difficult to
implement in any hygiene-bending system.
