Somehow I don't think you tested this :-)

* You have mismatched parentheses
* You assign to t, but never use the value
* you call b twice, once with no arguments, and once with 0 as an argument
* b is a block, but you call #empty? on it

Can you give an example of how this is supposed to be used?

Brian.
