deny_select? assert_no_select?

Rub.alicio.us:

assert_select has me spoiled. (I know I know there are alternatives. I have written them myself. But submit_form is true TFUI-style testage; it tests a form exists while submittting it, so assert_select is here to stay!)

However, where is deny_select? alias assert_no_select? How, besides rolling my own (from my assert_no_xpath) do I assert that an HTML gizmo does _not_ exist?
