    IMHO, stick to offsets in the first instance, this is a slice
    notation, first order of business is to make it behave like
    array_slice (+on strings). Assoc key based slicing feels pretty
    wrong to me at this point.
I have to agree, we are getting ahead of ourselves. A quick summary of what this RFC should cover: - Slicing an array or string based on the positional index. Things for future RFC consideration: - Slicing an array or string based on the key. - Index -1 for last item of list. Everybody agree that the only focus of this RFC should be the positional index slicing?

I'd be tempted to introduce the ability to get a single element by position as well, just because that would be a really useful feature, and "accessing array elements by their position" is kind of pre-requisite for "accessing a set of array elements by their positions" anyway. It might also make the rationale for the eventual syntax more obvious to those who haven't been reading this conversation. :) Regards, -- Rowan Collins [IMSoP]
