broadcast issue

[rveltz]

Hi,

In order to have AF working alongside with CuArrays, I would need the following to work:

a .= a  .+ b

but it returns

julia> a .= a .+ b
ERROR: MethodError: no method matching ndims(::Type{AFArray{Float64,1}})
Closest candidates are:
  ndims(::Base.Generator) at generator.jl:53
  ndims(::Number) at number.jl:67
  ndims(::Type{#s75} where #s75<:Number) at number.jl:68
  ...
Stacktrace:

 [4] materialize!(::AFArray{Float64,1}, ::AFArray{Float64,1}) at ./broadcast.jl:804
 [5] top-level scope at REPL[7]:1

Is it an easy fix?

Btw you should consider making AF a backend for GPUArrays

Thank you,

Best
