Re: [Boost-users] [mpl][fusion] iteration over mutiple containers

I may have confused some with my last post, ..but the mpl::for_each invocation doesn't align with the function call-operator of Func, rather, you'd rewrite Func's callable operator appropriately to match the for_each invocation. What I have today is a call like: Func<MyVisitor> ftor(...); ftor.operator()(Ctr[index]); Hope that kind of clarifies what may have been cause for some confusion. Looking forward to what others can say here.. --Manfred On Tue, 1 Jun 2010 21:37:33 +1000 Manfred Doudar wrote:

Hello,

I've been using the Boost.PP lately, and everything now works rather nicely, but there's been a thing in the back of my head that has always been telling me, that the problem is better suited to mpl/fusion. The problem in this case is I have "two things" that need to be iterated over, one a series of tags (aka "types"), and the the other, a runtime index.

I'll express what I'm after with mpl::for_each, because the issue becomes clearer that way:

using namespace boost;

//Func: is an object that facilitates visitation on algorithms
