Disables loop unrolling: a loop step is a single SIMD register, as with unroll<1>. The effect of unrolling is described on eve::algo::unroll.

std::vector<float> data(1024);
 
// One register a step: the body is long enough on its own.
transform_inplace[no_unrolling](data, [](auto x) { return eve::exp(x); });
