So the way to do that right now is:

But I agree that there should be a simpler way of doing this.. maybe
update can take a filter style block so update{ :exp += 10 } works?

How do you use this? Using == for assignment feels weird:

= UPDATE
DB[:table].update{ :a :a + 1 }
- UPDATE table SET a = a + 1
These work:
