I just don't like having to enumerate all possible fails, I'm too lazy.
Can't we be smarter about that? Could we do a {reason}x{bit-offset} like
thing?
Where we limit reason to a few simple things like:
invalid
out-of-range
not-supported
and have the bit-offset indicate the field we're having the particular
problem with?
Then all we need is a smart way to generate and map the bit-offsets
without too much manual labour.
