`a=[]` # you will get an `Array{Any, 1}` with zero size  
That’s not I want.

`a=fill(0::Int, 0)` # yes you can get a zero sized Array{Int64, 1}.

But `fill` as is suggested by its name should not be used to initialize an empty array, shouldn’t it?

`a=empty([0]) ` #yes this will also create a zero sized Array{Int64, 1} with zero size, but it is rather noisy, isn’t it?

What is the best way to create an empty Array of certain concrete type?

Thanks.

Or, if you prefer a more verbose but slightly more obvious approach, `Array{Int, 1}()` and `Vector{Int}()` will also work.
