Comment #17 on issue 1467 by smichr: sorting values with imaginary numbers  
in radical
http://code.google.com/p/sympy/issues/detail?id=1467

The original issue no longer causes a problem in the master branch...not  
sure what
fixed it.

###
C:\DOCUME~2\chris\sympy\sympy>\python26\python.exe
Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit  
(Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from sympy import *
>>> sorted([3,I])
[3, I]
>>> type(I)
<class 'sympy.core.numbers.ImaginaryUnit'>
>>> sorted([3,sqrt(I)])
[3, (-1)**(1/4)]
>>> 3<I
False
###

So before anything gets patched we should identify what the problem is  
that's being
fixed. Also...as mentioned above, we should probably patch to *downgrade*  
sympy's
abilities to make comparisons of things like 3 and I so 3<I raises an error.
