Fine. What's canonical or most basic example of where SIMD should be applied, but isn't because it's too tricky to do so?
In our shop, we never look to vectorize any function or process unless it's called inside a loop many times.

That seems to disqualify your example
There is none. That's a contradiction in terms. SIMD either fits the shape or it doesn't.
Try problem #1, parsing numbers.
