-//! These helpers provide a way to easily emulate a vectorized SIMD op on two SIMD vectors,
-//! except using scalar ops that iterate through each lane, one at a time, so as to remove
-//! the vagaries of compilation.
-//!
-//! Do note, however, that when testing that vectorized operations #[should_panic], these
-//! "scalarized SIMD ops" will trigger scalar code paths that may also normally panic.
