Demo

// Declare pa(c)ked types - their width is determinded at compile-time to match
// the largest possible vector register size for the target architecture.
pfloat x = ...;

if any(x > 2.0f) {
  masked(x, x < 3.5f) = x * x; // Use masks to select specific lanes
}

// Store vectorized outputs to arrays
float buffer[pfloat::width];
store(&buffer, x);

A working implementation of the mandelbrot fractal is implemented in kr8md_demo.cpp.
