|1= Python support would be a great feature I think. It is used in many products (e.g. in Blender) and that is a plus. However it's not guaranteed that it is free of such problems until you port all current Nasal scripts to Python and test it. What I am thinking about is a possibility to convert Nasal scripts to C or C++ and compile them as shared objects (.so .dll). Then we could load them dynamically at fgfs runtime. So in the end we get raw C/C++ performance to our modules. Is this possible or am I dreaming of something impossible here? What do you think? | |||

|1= Does anybody of you know how garbage collectors of Java and Python and other GPL'd script engines compare to each other? (atomic step character) | |||

|1= Reference counting doesn't provide a strong performance advantage over conventional garbage collection, and a reference-counting scheme can take an unbounded amount of time. Reference counting schemes that do have real-time or bounded behavior are very complicated. I don't know much about our Nasal implementation, but I suspect that the garbage collector could be changed to trace only a portion of Nasal's heap at each invocation, at the risk of increased memory use. | |||
