Fun with Boost::proto

So I am working on a theoretical blog post on expressions based upon some of the little nuances that I have learned over the last week. Some neat stuff. In my research I came upon a neat little series of articles called "Expressive C++" by Eric Niebler...

Icon 2 Comments
These instructions are for setting up FLTK v1.3.0 in VS2010.

I am using VS2010 Express SP1.

Over the years I have written a few stream manipulators and one thing that has kind of confounded me is a way to save persistent information for each stream. Well today I found a way.
