Oh, interesting.

Then I have a new goal: understand that. :-)

That may be the issue, because I am using the latest git head. There
were only very small issues, but I thought I should fix them anyway.
Specifically,
 - some records weren't listed with a 'src' slot
 - the first two slots for <letrec> were out of order
 - it documented <sequence> instead of the newer <seq>, which has a
slightly different structure

The attached patch fixes all of these, I think.

Have a good day,
Noah
