Hi-
The issue of live vs. static lists is actually orthogonal to my
main question (though that would be a relevant argument to bring to
the Selectors spec, which uses a static list... I think that ship
may have sailed, though).
The functionality I was requesting primary feedback on was whether
or not to include an interface in the ElementTraversal spec which
would provide a list of elements (not nodes, which could include
spaces and line breaks, etc.) that are children of the context
element.
I suggest leaving this out, because it's not possible to implement
both next/previous and indexed access in a way that is efficient for
all cases (it's possible to make it fast for most cases but pretty
challenging to make it efficient for all). This is especially bad
with a live list and an element whose contents may be changing while
you are iterating.
If all you care about is looping through once, writing the loop with
nextElementSibling is not significantly harder than indexing a list.
