There seems to be some misunderstanding about the usage of unsigned char in the register_move usage and interface. This is not at all about limiting register numbers < 256, but it does limit the amount of params/args inside optimized tail-recursive calls to 255. I.e. the limit is for the amount of positional function arguments. Another Q is: do we limit the amount of positional args? leo
