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?

Well, I read it from left to right and therefore I found it more natural
for me to do it this way. However, msm-lite supports both syntaxes.
You change it to dst_state == src_state by setting
up BOOST_MSM_DSL_DST_STATE_FIRST. Currently the default is src == dst but
it might be changed
to the, less confusing, one if that what devs are more comfortable with.

You can find an example here ->

Cheers for the question, Kris
