What is that nonsense supposed to be?
I fear this conversation is becoming uncivil.
Sorry, I just couldn't make sense of what this is supposed to be, and used bad phrasing.
What would the value type of that range be?
int
That's what "if" statements are for.
We want to avoid these.
Actually, you don't need them. This is really simple; it's just like processing a deque.
Unless you process the uneven end bits with non-SIMD code.
I would quite like a provide a way to do this. A range, however, must be homogeneous, and have all its elements be the same type, so it's either a scalar or a vector, can't be both.
That's where your problem is; you can't look at the "vectors" as elements. They're just views used as an optimization technique for operating on subsequences of a particular number of scalars. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
