Re: Yet another idea

C++ iterators is something I'm trying to hide.. If we can't find a
good way to present embedded loops, then the whole idea is useless.

I'm trying to imagine how we can use it.. Something like:

    "  topic template 1 here ",
    SubTopics.forEach( " subtopic template here "),
   "  topic template 2 here "

It isn't a problem to implement variable number of parameters. It's a
problem then we have too much C++ again :(
