Good question! That interface asserts if the width is invalid whereas the
`printPretty()` interface will still emit output. I went back and forth on
which way to go (I wasn't able to come up with a test case where
`getBitWidthValue()` would trigger an assertion, but I still wasn't comfortable
going that route). I can switch if you think it's worth it.
