Since then I have always tried to keep the end user experience foremost in my work. "Many bugs that would be hard to fix" is not a given. I cannot count the number times I have replaced recursion with iteration. With discipline (no other changes to the algorithm) it is a straight forward conversion. I agree that merely being able to handle large files is not a strong justification. OTOH, in spite of running on a state of the art desktop with 64GB RAM, 4GHz+ multi-core processor and high-end gamer graphics Emacs feels progressively less responsive. Any work countering that trend gets my vote. /john
