Do you need to decay the ExPolicy here (and in other places)?

Do we really need decay over here? ExPolicy is only being used for deducing if seq or unseq overload should be called. is_unseq<unseq_policy> should be true for both value and reference right?

Also, please note that this is branched from simd-find.

Well, you tell me. I was just asking the question without closer investigation.

To the best of my knowledge, I don't believe we need to decay. I am unsure why it was being decayed previously. I assume is_unseq<unseq_policy>, is_unseq<unseq_policy&> and is_unseq<unseq_policy&&> all evaluate to true

@hkaiser I have tried checking behaviour with/without std::decay_t. The correct overloads are called in both cases. I am unsure why std::decay_t is being used.
