I am trying the first example from https://github.com/chriselrod/LoopVectorization.jl . That is:

```
using LoopVectorization, BenchmarkTools
function mydot(a, b)
s = 0.0
@inbounds @simd for i ∈ eachindex(a,b)
s += a[i]*b[i]
end
s
end
function mydotavx(a, b)
s = 0.0
@avx for i ∈ eachindex(a,b)
s += a[i]*b[i]
end
s
end
a = rand(256); b = rand(256);
@btime mydot($a, $b)
@btime mydotavx($a, $b)
a = rand(43); b = rand(43);
@btime mydot($a, $b)
@btime mydotavx($a, $b)
```

I get an error from “s += a[i]*b[i]” which is

ERROR:LoadError: “Don’t know how to handle expression:\ns += a[i] * b[i]”Stacktrace:

Am I doing something dim or is this a bug?
