This required a massive cross-cutting rework to the scope system, multiple subtle bugfixes and relearning of the parser internals, but it does appear that functions are working correctly. A few caveats: for now, parameters are always constant, regardless of type, return values can't be specified, and some script tests have been written. Most importantly, a key feature is working: closures.
