Hi, Hi. Here's a preview of Phoenix V2. This will probably be the last release of the library. Phoenix V2 will be the basis of the Phoenix and Boost.Lambda merger. You can get it here: http://spirit.sourceforge.net/dl_more/phoenix-2.zip You can browse the draft docs here: http://tinyurl.com/6crgp What's new? A lot. This is a total rewrite based on earlier discussions with Jaakko Jarvi. The library's is built on top of Fusion and of course MPL. Of particular interest are local variables and lambda-lambda scopes: http://tinyurl.com/3mn6w There is also a set of lazy functions that work on STL sequences (e.g. push_back etc.): http://tinyurl.com/46bbm and pretty soon, a final TODO item (built on top of scopes/ lambda), lazy STL algorithms (e.g. find_if, etc). The scopes section (link provided above) in the docs illustrates how to write lazy functions that accept higher order functions (e.g. for_each).
