initial v1 1 Looking at the patch, I see presently special work happens on maxima's return values, which replaces maxima's "inert" sum with sage's newly grown symbolic sum function. I think that's problematic (for instance, we could have nested sums, and the nested sums would escape this treatment). 1 Looking at the patch, I see presently special work happens on maxima's return values, which replaces maxima's "inert" sum with sage's newly grown symbolic sum function.

Isn't the line
