reviews for symbolics bug fixes

[Burcin Erocal]

Hi,

I just uploaded a new pynac package and patches which fix

#6404 conjugate typesetting
#6401 typesetting real and imag
#6243 fderivative hash collision
#6377 exp evaluation at infinity

on trac. The package is here:

http://sage.math.washington.edu/home/burcin/pynac/pynac-0.1.8.p2.spkg

It would be good to include these in the 4.1.1 release. Are there any
volunteers for reviews?

Thanks.

Burcin

It would be good to have these tickets reviewed for 4.1.1, since we
have been receiving reports of doctest failures in the module

devel/sage/sage/symbolic/expression.pyx

Hi,

Thanks Burcin. Surely, it would be good to have them fixed in
the next release.

If no one else reviews it within next couple of days then I will be
happy to do so, as I am travelling right now.

Cheers,
Golam

Yep, it would have been good to fix a few more, but I don't think I can
spend more time on this till the release. I just wanted to get some of
the stuff I had on my laptop out there.

Note that the new package also supports a flag to disable chain rule
for symbolic functions. This will definitely be useful for constructs
such as symbolic integrals, sums, products, limits, etc.

It should also pave the way for a fix to #6465. Maybe you can take that
up again?

Thank you.

Thanks Burcin. OK, I got that (#6465) fixed using the option for disabling
chain rule. I will wait for the next release before I put up a patch.
