I see. That does seem helpful once you consider how these types compose, rather than thinking about a one-off conversion. However, I think it would be cleaner to have a library that auto-generated a parser for a given struct paired with an endianness specification, rather than baking the endianness into the types. (Probably this could be achieved by template metaprogramming too.)
