Обсуждение: function definition and "entity"

I've to refactor a bunch of functions.
Some of them are called inside other functions.
Most of them could be changed through create or replace so...
calling function should still refer to the right newer function.

But some had to be dropped because the change was in output param.

Is there a way to automatically check if all references are to the
correct existing function?
