Re: [boost] [MSM] Is there any interest in C++14 Boost.MSM-eUML like library which compiles up to 60x quicker whilst being a slightly faster too?

I would be interest just because of these 2 points. I see a lot of opportunities to use such library but most of the time I can't afford to use Boost.MSM because of the implied compile-time cost.

Thanks for your feedback and yea, Boost.MSM is great; eUML is even better, but it was written some time ago, before C++11. It still uses Boost.MPL and Boost.Fusion which are pretty slow to compile in comparison to what can be achieved nowadays. On top of that, right now we have a lambda expressions which were emulated in eUML using Boost.Phoenix. All in all, C++11/14 give as a lot of opportunities to improve the situation and Boost.MSM-lite is just a small example how much more user-friendly C++ might be as well as how much faster the code might be compiled without loosing any performance.

Dear Boosters,

I have recently released 1.0.0 version of experimental C++14 Boost.MSM-lite. Your scalable C++14 header only eUML-like meta state machine library with no dependencies, which outperform Boost.MSM - eUML in: - faster compilation times - up to 60x times faster! - smaller executable size - up to 15x smaller

- slightly better performance - smaller memory usage - short error messages
