You're still confusing code readability with getting an overview of a class. They are two different things.Requiring IDE assistance to make code _readable_ seems completely fail to
me.
1) You're not always reading code in your IDE, often in commit logs, diff
windows, emails, chat clients.
2) With so much hate for IDE support, it seems like a massive contradiction
to say that an IDE should be required to make code readable.
Reading code is the most fundamental task in programming. Anything that
gets in the way of code readability is an epic fail.
If you need an overview that you can view in text, add comments at the top of the class with a method signature on each line. That will give you the overview you need and reproduce the total nightmare of keeping it in sync with the methods. Something you would also have to do with separate declarations and implementations.
