Non default positive strides are very handy, but negative strides seem weird to me. Not the negative striding exactly, but the way fenceposts and negative strides interact.

For example, this poster seems to posit a canonical WTF with negative strides.

I can almost picture Picard saying "WTF do you need to omit the end index to get the zero element??!!"

Readability counts, no? Just reverse it and use positive strides.
