Don:
Simd comparison generally doesn't return a bool, it returns a
bool array,
one per element.
Does (arr[] < 10) mean "is every element in arr less than 10"
OR "is any element of arr less than 10" OR "create a bool array
which is true for each element which is less than 10" ?
All make sense. That's the problem.
Right, it's a design problem.
I think the right thing to do is to take a look at what's an
efficient operation to do in hardware (and then look at what's
the most commonly useful operation for users). I think the right
design here is to return a bool[N].
So in this case monarch_dodra has to add some more code to test
all/any.
