[Numpy-discussion] adding numexpr user-provided ufunc evaluation

[John Salvatier]

I am thinking about building a patch to implement user-provided ufunc
evaluation for numexpr as was discussed in this thread
http://www.mail-archive.com/numpy-discussion@scipy.org/msg26292.html. Does
anyone have any advice for learning/understanding the numexpr source and/or
suggestions about implementation? All advice is helpful :)

Francesc Alted mentioned that Mark Wiebe's other NEP
https://github.com/m-paradox/numpy/blob/mw_neps/doc/neps/deferred-ufunc-evaluation.rst,
would provide this feature (along with many other benefits). It looks really
amazing, but I don't have a good sense of how developed it is.

Best Regards,
John Salvatier
