These I did mindlessly to preserve the result:
{{{
Failed example:
QQbar(e^(pi*I/3))
Expected:
0.500000000000000? + 0.866025403784439?*I
Got:
0.50000000000000000? + 0.866025403784439?*I
}}}
This one cannot be fixed otherwise:
{{{
Failed example:
a.composition(exp(I*pi/3), exp)
Exception raised:
File "/home/ralf/sage/local/lib/python2.7/site-
packages/sage/symbolic/expression_conversions.py", line 866, in
composition
operand, = ex.operands()
ValueError: too many values to unpack
}}}

How do you let the original succeed? Attempts with tolerance didn't work:
{{{
sage: N(integrate(sin(x^2)/(x^2), x, 1, infinity))
0.285736646322853 + 6.93889390390723e-18*I
}}}
> By the way, I think that this should be pynac-0.6.0 instead of
pynax-0.5.4.
Because of the interface change or the amount of changes?
