On a 64-bit system, typemin(Int32):typemax(Int32) is a legal Range who's length is strictly Int64. Should this be allowed? In that case, rand() breaks down.

julia> r = typemin(Int32):typemax(Int32)
-2147483648:2147483647
julia> typeof(r)
Range1{Int32} (constructor with 2 methods)
julia> length(r)
4294967296
julia> rand(r)
integer division error
