I for one can't edit large programs - period - without IDEs. Refactoring is not optional once a program exceeds a certain size. A lot of problems that people try - usually unsuccessfully - to catch with tests simply don't occur with refactorings.

And I notice the same about Go programs that I used to have with python programs. They grow and grow, and beyond a certain size, the basic architecture "freezes" and no more changes are possible because nobody can fully grasp all consequences of edits.
