--- Comment #1 from John Colvin <john.loughran.colvin at gmail.com> ---
The documentation says that a digest must implement a put function that takes a
variadic number of individual ubytes or a ubyte array. This is a stronger
requirement than being an output range for ubyte and ubyte[].

It is possible to argue that std.digest should work for output ranges in
general, but that's an enhancement request. It probably wouldn't be a lot of
work to implement, but you might be the only person for whom it's a priority...

If you found the documentation confusing or lacking, please feel free to make a
pull request to improve it.

If you found the error message confusing or lacking, that's also something that
can probably be easily improved, or at least explicitly reported here.
