Interesting. The editor clearly has to know the syntax of the
language, and some of the semantics.

I can see using ASIS to get there with Ada, but it would have to run

I do this on occasion, and GNAT doesn't provide much help in
identifying what needs to be removed. I think the "require override"
feature in Ada 05 will help here.
