I'll be glad once this is all implemented. I recently rewrote most of my functions that took abstract vectors and matrices to instead take concrete arrays along with a few index parameters. I did this because I realized SubArrays were making huge memory allocations inside the tightest parts of my loops for some unknown reason. Since I didn't want to spend days debugging that weirdness, I just took the simpler (but cruder) option of passing in the "kitchen sink" to each function.
