The code here:
http://svn.boost.org/svn/boost/sandbox/variadic_templates/sandbox/slim/
might be helpful. It was based on Chrisopher's code but had to be modified slightly as mentioned in the post:
http://comments.gmane.org/gmane.comp.compilers.clang.devel/24145
which also mentions the slow compile times when not using the preprocessor.
Compilers appear to have improved since then! I decided to take gcc4.8.1 and fusion::map for a spin, since I happen to have a variadic implementation of map that does not use recursion. The results of this crude exercise can be found here: https://gist.github.com/K-ballo/a44590159133997abcdc
This link only has the test driver code and the test results file. Could you please provide a link to the implementation of this non-recursive map?
Certainly, you can find the proof of concept implementation I used for the tests here: http://fusionfenix.com/ktests/boost.fusion.map.zip It is intended to be used with Boost.Fusion from trunk, you just need to replace fusion's "map" directory with the "map_" one in the zip. Keep in mind that it is just a proof of concept. I am working on a full fledged implementation as time permits, which is not as often as I would like.
