why 'lambda' and 'reduce'?

In fact, I wrote: "while it is obfuscated, it is not very

Indeed, perhaps you concealed how the error control works more
cleverly than you concealed how everything else works.

That *I* don't understand the error control, however, is hardly
compelling evidence that it is cleverly obfuscated; rather, it is
evidence that I am ignorant of numerical analysis, as admitted in
my review.
