INFO: Testing ArrayFire

Warnings for deprecated syntax:
"typealias AFVector{T} AFArray{T,1}" at ArrayFire.jl:20. Use "AFVector{T} = AFArray{T,1}" instead.
"typealias AFMatrix{T} AFArray{T,2}" at ArrayFire.jl:21. Use "AFMatrix{T} = AFArray{T,2}" instead.
"inner constructor AFArray(...) around ArrayFire.jl:13". Use "AFArray{T,N}(...) where {T,N}" instead.
"typealias dim Int" at defns.jl:78. Use "const dim = Int" instead.
Base.LinearIndexing is deprecated, use Base.IndexStyle instead. near /indexing.jl:125
