I hope you had as much fun fixing it as I had isolating it. That
was one of my most grueling rounds of golf yet. Macros, covered
lets, exceptions and lists of lists which aren't always lists,
spread through several files in two languages.

On a related note I hate macros.

By the way you spelled my name wrong in the commit with the regression
test the other day. It's got an haitch in it.

(I don't really mind you should see how they mangle it in Cyrillic
I'm just pedantic)
