John Colvin:
I think the right design here is to return a bool[N].
...
There is significant opposition to any simd operators that
allocate. The reasoning is that they appear fast but are in
actual fact slow (for most normal size vectors, the allocation
would be much slower than the calculation itself).
I love the features of numpy and matlab etc. when it comes to
array operations, many of which allocate implicitly, but Walter
and others were quite adamant they they do not belong in D, a
position I've come to agree with.
Can't D allocate that bool[N] on the stack?
