That looks good in principle. I see it as being valuable and important that
users can define generic relational operators/functions, meaning ones that can
work with any relations like built-ins can, and the ability to iterate over
record fields, or at least introspect a relation to see what fields it has, is a
good foundation to support this. -- Darren Duncan
