Hello,
I was just wondering whether there are plans to add the zip_iterator based on fusion to CVS HEAD. The following post mentions it:
Only when we can do it without breaking anything. That means:
0. boost::tuple is a valid fusion tuple
boost::tuple is a valid fusion tuple. I don't understand the reason for this requirement though.
Because the current zip_iterator operates on boost::tuple. If we change it to use fusion under the covers, it should continue to work with boost::tuple or we'll break code.
1. The subset of Fusion we use works on all the same broken compilers, or
No, sorry :( But can't we keep the ifdef?
"Keep?" I think you mean "add." I guess we could add one; it's not a big win in my book, though, since people can use boost::tuple with fusion. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
