[boost] Re: mpl::inherit_linearly reuse to produce loki's tuple?

Could inherit_linearly be used to create something like loki's tuple? The name, inherit_linearly, and a very brief look at the code suggests it does something like loki's GenScatterHeirarchy, which was used to create the loki tuples as shown in:

http://cvs.sourceforge.net/viewcvs.py/loki-lib/loki/Reference/HierarchyGenerators.h?rev=1.5&view=auto

Yes it can be used that way.

If so, then I was wondering if it would be worth it to reuse inherit_linearly to implement boost's tuple?

I don't think so. What would we gain by it? The successor to Boost.Tuple is described in http://www.boost.org/libs/spirit/fusion/readme.txt. Since fusion tuples are "flat" structures, there's no win in building them by repeated folding of an input sequence. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
