Comment:
It doesn't appear that you messed anything up, except ...
{{{
sage: arg(3.0)
---------------------------------------------------------------------------
<snip>
1426 return x.arg()
1427 except AttributeError:
-> 1428 from sage.rings.complex_field import CC
1429 x = CC(x)
1430 return x.arg()
ImportError: cannot import name CC
}}}
So apparently that won't work. Otherwise the changes are fine.
