Adam, thanks a lot. That worked. But when extending to my "real world" use case I'm running constantly into troubles. There are still some issues with file streams. cout mostly works but ofstream doesn't.

Attached is a file with my use cases. These are very basic usages of phoenix and I think they should work.

Thanks, Christian

AFAIK, phoenix gives std::cout special treatment in regards to being implicitly captured by reference.

Wouldn't it be easier/more appropriate to provide extraction operator overload for your point struct and then just: std::copy( pts.begin() , pts.end() , std::ostream_iterator<point>(out, "\n")); The point members could be streamed using transform_iterators. Jeff
