How to initialize an array of dicts? Is there any suggested ways to do it?
julia> (Int64=>Int64)[]
Dict{Int64,Int64} with 0 entries
# And since brackets creates Arrays:
julia> Any[]
0-element Array{Any,1}
# So I suppose this would generate array of dicts, until it fails:
julia> ((Int64=>Int64)[])[]
ERROR: `getindex` has no method matching getindex(::Dict{Int64,Int64})
