I *heart* that sort of query syntax.  You'll see much the same thing in the 
Kansas ORM:

results = ksdbh.select(:Planes) {|r| (r.country == 'USA') & (r.speed > 350)}

In this case, method_missing magic is mixed into that in such a way that the 
Ruby code becomes a SQL statement for querying a relational database.

It's a great way of interacting with data.  Neat to see that KirbyBase is 
doing that.
