Currently, Julia defines

typealias StridedArray{T,N,A<:Array}  Union(Array{T,N}, SubArray{T,N,A})

It seems like it would be better to define

abstract StridedArray{T,N} <: AbstractArray{T,N}

and haveArray andSubArray both inherit fromStridedArray.

The reason is that I would like to define a newStridedArray type (wrapping a NumPyndarray). There is no reason, as far as I can tell, that I can't provide all the functionality of aSubArray and be used everywhere the latter is usable, but currently it does not seem possible to do this. Changing toabstract StridedArray would fix this.
