[julia-users] rand(x::Int32) doesn't exist, omission or intentional?

[Jeff Waller]

Seems like the intention is to cover many possibilities.  This would be the 
typical rand but with type Int32 not Int64  for example.

*julia> **rand(2)*

*2-element Array{Float64,1}:*

* 0.690068*

* 0.137219*

*julia> **rand(int32(2))*

*ERROR: `rand` has no method matching rand(::Int32)*

Is there a reason for this just kind of got overlooked because the usage is 
rare?
