Maybe "vectorize(v op e)" ?
Implies implementing via SIMD instructions.

That still seems odd to me. If "v += e" means "append", then I might
expect "v + e" to do the same, except producing a new value w/ original
vector not modified.
Maybe that's a less common use-case, though, and so "v op e" being an
error would be less weird than suddenly changing the meaning of that
operation.
