1) Static members and static functions inside class can be accessed as ModuleName.ClassName.FunctionName (MemberName respectively). Old way aka ModuleName.ClassName_FunctionName still works. 2) Same goes for enums inside classes: ModuleName.ClassName.EnumValue1 etc. 3) More 'runme' tests for lua + modifications to existing tests to test new changes. Code is loosely based upon python implemenation of the same thing. Patch #62.
