[New-bugs-announce] [issue4290] 2to3 fails with sympy

[Ondrej Certik]

New submission from Ondrej Certik <ondrej at certik.cz>:

Download my branch of sympy from here:

http://github.com/certik/sympy/tree/division3

and run the 2to3 tool with python2.5:

$ python2.5 ../2to3/2to3 sympy/
[...]
Traceback (most recent call last):
  File "../2to3/2to3", line 6, in <module>
    sys.exit(main("lib2to3.fixes"))
