It appears that fftshift and ifftshift are type unstable:

julia> @code_warntype fftshift(rand(ComplexF64,64,64))
Body::Any
...
55 ─ %140 = invoke AbstractFFTs.circshift(_2::Array{Complex{Float64},2}, %30::Array{Int64,1})::Any
└───        return %140

Or am I doing something wrong?

I'm running Julia v1.1.0 with FFTW v0.2.4.
