Heh, indeed. I just spoke briefly with lrz, and he's optimistic that we can
make it work. One question I have, though, would be if you intend to allow
variables as default values or only literals. For example, should this work:

    x = 30
    def foo(a: 1, b: 2, c: x)
        puts [a, b, c]
    end
    foo(a: 10, b: 20) #=>  [10, 20, 30]

?
