Error: "Don't know how to handle expression: ..."

Hi @chriselrod,

something seem to be broken in version v0.3.10. i get

"Don't know how to handle expression:\nzre += xre[i] * Are[i, k] - xim[i] * Aim[i, k]"

when executing

using LoopVectorization

function test_avx(xre::Vector{T}, xim::Vector{T}, Are::Matrix{T}, Aim::Matrix{T}, k::Int) where {T<:AbstractFloat}
    zre = zero(T)
    zim = zero(T)
    @avx for i ∈ 1:length(xre)
        zre += xre[i]*Are[i,k] - xim[i]*Aim[i,k]
        zim += xre[i]*Aim[i,k] + xim[i]*Are[i,k]
    end
    return Complex{T}(zre,zim)
end

function test_avx(x::StructVector{Complex{T}}, A::StructArray{Complex{T},2}, k::Int) where {T<:AbstractFloat}
    return test_avx(x.re, x.im, A.re , A.im, k)
end

test_avx(b, A, k)

I'm sorry.
From now on, I will wait until CI is green before tagging a new commit.

A fix will be here within the hour.

Thank you so much

This is fixed in 0.3.11.
