Nicolas Cannasse released a new version of haXe and now the announced Flash 9 support is integrated.
A haXe tutorial for Flash 9 is already online.

There is also SWHX to build crossplatform haXe desktop applications with e.g. Flash as the frontend. In one word haXe tries to solve all problems with one language. From my point of view it currently only lacks of a productive IDE to program haXe but this will only be a matter of time. Currently a project called HXDT, a plugin for Eclipse, has already been started but the last update was in December 2005 and Flashdevelop also provides a haXe-plugin.
