I actually think it is cleaner to not use the record matcher (since it
is constructor order dependent). You can use the "field" (i.e. procedure
result) and predicate matchers, `=` and `?`, to do it like this

```
(match record
   ((? my-record?
       (= my-record-field-a a)
       (= my-record-field-b b)
       ...)
    ...)
```

using the exported predicate and accessor procedures.
Thanks, I did not realize it is possible to do that, seems exactly what 
I was looking for.
