Both patches should be applied.
I added an indirect doctest. I give myself a positive review, feel free to correct me if you disagree.

Hi there, it is embarrassing how bad my naive original code was. Here's a comparison (for the release tour)
Old*
*New*
The code looks good, doctests pass.
The only issue: the
sage -coverage
script will pick up_walsh_transform
and complain that it isn't documented and doctested.Of course it is impossible to doctest this inner function directly, but the keyword
# indirect doctest
will do the trick.This is a positive review except for the missing documentation.
