This library seems to differ - it appears that there are criticisms of the library's performance characteristics, but no-one is pointing to alternative libraries that solve these problems (albeit they may be deficient in other ways). Similarly, I haven't noticed any suggestions for specific techniques that might be used to improve the performance of the current submission.
To the contrary, in previous threads I have posted several examples of small FSM libraries with either O(1) or O(#outgoing transitions) dispatch. Alexander Nasonov has also posted some examples using a very different approach.
These techniques do not address the issues of state machines dispersed across multiple translation units, or support for orthogonal states, do they? Matt
