[julia-users] zero cost subarray?

[Peter Brady]

Inorder to write some differencing algorithms in a semi-dimensional 
agnostic manner the code I've written makes heavy use of subarrays which 
turn out to be rather costly. I've noticed some posts on the cost of 
subarrays here and that things will be better in 0.4.  Can someone comment 
on how much better?  Would subarray (or anything like it) be on par with 
simply passing an offset and stride (constant) and computing the index 
myself? I'm currently using the 0.3 release branch.
