Array{Int}() gives strange result

[garrison]

As noticed here, Array{Int}() fails on julia 0.3:

julia> Array{Int}()
ERROR: type cannot be constructed

but leads to a rather weird result on master:

julia> Array{Int}()
0-dimensional Array{Int64,0}:
-1229782938247303442

This behavioral change was introduced in 23a6995.

Did you read the two issues that that commit closed? What would you suggest?

[garrison]

I did. But I'm not quite sure what the -1229782938247303442 is about. If making a 0-dimensional array is really what we want to do in this case, then I'd suggest removing whatever is causing that to be displayed.

[garrison]

Sorry, I just had the epiphany that a zero-dimensional array is a scalar, and this is simply an uninitialized scalar. I guess this will be "fixed" by #9147 if that is implemented as planned.

[garrison]

But as a new user, I would find the current behavior rather confusing.

Closing it as a dupe of #9147.
