Indeed, not many support full error checking for C++ in realtime because of its complexity...
But checking syntax errors (like: YOU FORGOT THE ; BAKA!!!!) or some basic flow errors (like: your function does not have a return statement) is possible.
But this was just for curiosity, what I really want to know is the diffrence between 8.02 and the current SVN, and no, I will not read the entire SVN, I do not want to know that you fixed the source files that had the comments aligned wrong or that sort of stuff. I want to know like: WE IMPLEMENTED A WHOLE NEW TOTALLY AWESOME LUA PLUG-IN SYSTEM!, I know that this is not true, it is just an example of a actually important feature, that you should have (the type of feature, not this particular one) in a updated roadmap as done or to-do.
