it's Logic::_scriptVars[ID] instead of just ID. Apart from looking cool, it makes it much easier to tell the difference between variables and constants when looking at the code. Of course, this sort of sweeping changes is jolly good for introducing truly weird regressions, which is why I waited until after 0.6.0. svn-id: r13331
