I can easily think of logic requiring nested conditions of any type, EVALUATE included.

I can also think of how easy it is to test this, rather than just asking.

Always remember that 98% of the life of a program is maintenance. My rule of thumb was always never to go beyond 3 levels of "nested". There is no reason to. Over the years, I saw programs that included pages and pages of nested "ifs" - first of all, it is very difficult to debug - we called them "the flying wedge". Second of all, it is not efficient. Do an evaluate (if) and then a perform - go to the exit of a paragraph.
