Hi John,
`help(Array)` is telling you to use Array(SomeType, some_num_of_dims). If
it was telling you about the type it would look more like this:
> help(Int)
DataType :
Int64
supertype: Signed
The `Base.Array(type, dims)` line at the top of the help is giving you the
calling signature. Since Array is both the type name and a method to
construct arrays, it can be used with both {} and (). Try this:
> typeof(Array{Int, 3})
DataType
> typeof(Array(Int, 3))
Array{Int64,1}
> typeof([1, 2, 3])
Array{Int64,1}
