Well, that's an impressive debugging job. Just like Bruce Lee, you don't want to do anything halfway, it has to be perfect. And you're not to be messed with. (^.~)☆
I think this might be worth telling the shinnoid. I cannot see any obvious contact info on http://synthcode.com/scheme/irregex/ but his git commits on https://github.com/ashinn/irregex are by "Alex Shinn <alexshinn@gmail.com>". Well, at least he's not one of those protonmail people. If someone could drop him a line, that would be great.
Let's file a PR then, maybe it's worth linking to this thread?
