Would be great to have some higher order datatypes built in, like perl or python does: lists, hashes, etc. as well as the ability to build your own. Pre-made ones would be easier for those with less of a programming background. Ideally, if you could access all the namespaces themselves as a dictionary like python can, it would also provide a way for people to make their own savegame mechanisms that didn't get broken for compatibility every time the game is recompiled.
