- Fixer for the execfile() function on Py2, which was removed in Py3.
- The Lib/lib2to3/fixes/fix_execfile.py module has some problems: see
- python-future issue #37. This fixer merely imports execfile() from
- past.builtins and leaves the code alone.
- Adds this import line::
- from past.builtins import execfile
- for the function execfile() that was removed from Py3.
