I meant in sage. No issue in sympy. sympy-0.6.6 works fine with sage,
0.6.7 doesn't and the stuff that I pasted is the only thing one should worry
about. Of course sage test like:
sage -t -long -force_lib "devel/sage-
main/sage/symbolic/expression_conversions.py"
**********************************************************************
File "/usr/share/sage/devel/sage-
main/sage/symbolic/expression_conversions.py", line 559:
sage: f._sympy_()
Expected:
-asin(pi + x)/y + exp(x**2)
Got:
exp(x**2) - asin(x + pi)/y
**********************************************************************
File "/usr/share/sage/devel/sage-
main/sage/symbolic/expression_conversions.py", line 591:
sage: s.arithmetic(f, f.operator())
Expected:
2 + x
Got:
x + 2
**********************************************************************
should be fixed but they are trivial (notice it is a sage test :) )

A little grepping turned:
sage/symbolic/expression_conversions.py: return sympy.symbols(repr(ex),
each_char=False)
as the only location. I'll remember to remove it when we upgrade to 0.7.0,
thanks for the tip.
