2to3 . --fix raw_input -wpn
Py2 input is the new Py3 input wrapped in eval tags.
The new input is the old raw_input.
This lets you have the old behavior. Mechanical.

2to3 . --fix dict -wpn
Py2 dict was a list by default, the iterator versions
were switched around to be the default.
This lets you have the old behavior. Mechanical.

Make essential Tauthon's builtins and modules available in sandboxes, without
disrupting building with Python 2.7.
1. Allow new builtins and modules. "__build_class__" is for
building... new-style classes (to handle the new metaclass syntax imported from
3.x). "_oserror" is necessary because of internal changes to raise errors
deriving from OSError (which are reported as IOError if not caught).
2. Look for modules and packages in the right places.
This was tested on FreeBSD, and should work out of the box on Linux.
