This is what I've scribbled so far as a list of to-do items:

  - add hash_append_range taking a range
  - add a "provider" argument (providing the hash_append API) to tag_invoke
  - example of hashing boost::json::value
  - maybe change argument of tag_invoke to take the value by pointer, rather than by reference
  - maybe expose has_tag_invoke to users so they can specialize
  - make byte sequence seed constructor take `void const*` as well
  - change get_integral_result to take a Hash, instead of h.result(), so that it can invoke result() more than once
  - a user-accessible way to test whether a hash algorithm conforms to the requirements
  - add a variadic hash_append overload
  - hash_append_unordered_range: use more than 64 bits for intermediate hashes (uint64_t[4]); improve somehow

  - acknowledge https://github.com/HowardHinnant/hash_append
  - in documentation, focus more on the std::hash case, rather than on the md5sum case
  - in FNV-1a byte seed constructor, include the seed size
  - change block_size to std::size_t
