It sounds as if we are talking past one another. If you have a network = protocol that is somehow defined in terms of the size of fixnums in a = particular build of Emacs, then yes, I'd say that most people would = think that your code should make that explicit. But you certainly don't need lsh to handle arbitrary binary data; it's = not even convenient. I'm not saying that you are wrong; perhaps I don't = understand your needs. We could add functions for depositing and extracting bit fields in an = integer, basically encapsulating the common shift-and-mask operations. = That would make bit field manipulation less error-prone without = compromising speed or portability.
