I have already suggested such an alternative to segmented iterators (where I had a few misconceptions about segmented iterators, I thought they broke compatibility, but they don't, they still maintain the legacy non-segmented interface) there: <http://thread.gmane.org/gmane.comp.lib.boost.user/61636/focus=61647>, with an example of how you could use that to iterate over a binary tree there: <http://www.boostpro.com/vault/index.php?action=downloadfile&filename=generator_iterator.zip&directory=> Converting from those things to a pair of iterators is possible through the use of a coroutine, as demonstrated in the example.
I would like to have feedback on the general idea of providing tools to use SIMD with iterators and related algorithms,
+1!
and ideas about whether there is sufficient interest in the alternative to iterators for me to develop them. The intent would be to submit both the alternative to iterators and the SIMD helpers to Boost.
Now that your misconceptions about segmented iterators are cleared up, could you give a brief rundown of your alternative and its advantages? If all I have to do is read your earlier post and ignore claims of broken compatibility, just say so, but I don't want to waste time trying to decipher it if it's substantially wrong.
