Much better exception handling - Have them make more sense. Get rid of the multiple traceback prints, one for each level of catchs on python3. Also improve traceback on both python3 and python2 to exclude the function wrapper, and instead follow the execution frame. Downside is that neither form compiles on the other python, so have to use exec...
