Ah, I see. I'll have to try that.

Meanwhile I wonder how I can pass arguments to the constraints. 
I got two scenarios: 
    I'd like the user to type in a password, and repeat it and then check
    that they match. So I'd like a :equal-to 'password, but I haven't 
    figured out how to pass an argument to the constraint function.

    Another scenario is that I want a :unique 'table 'column check that
    looks up in my database. Again, I need to pass arguments to the 
    function. 

Any hints?
