Probably not an actionable item unless @farzonl has any ideas
The notes here feel quite unhelpful from a user perspective. I'm guessing the
error is that `int` doesn't fit in `int16_t` but if I was a user and I saw this
error then I'd be extremely confusing by what's actually wrong. That said the
actual error at least points at the function and tells you it's the wrong
overload so maybe not
