Subject: Testing for warnings

Is there a way of asserting that a warning is raised in a unit test?  
So I could write something like:

assert_warns "Blah blah" do function_that_warns(foo) end

I can't seem to find anything in the test/unit docs, but it seems  
like something that would be relatively common to test for...
