Generating a Java program with 90% less code

Is this really true? The hard part of renaming a class isn't usually changing the name Foo -> Bar, it's finding all the variables with type Foo named stuff like result_foo and renaming them result_bar. Can it help with that?

Static typing can help with a lot of things but it can't fix this error:

    pub fn add(a: i64, b: i64) i64 {
      return a - b;
    }

Actually, it kind of can:

The above link refers to the following Idris code:

  add : Int -> Int -> Int
  add a b = a - b

  addTest : add 4 5 = 9
  addTest = Refl

That unit test would be just as easily implemented with dynamic typing.

yes, intellij for java will also rename all local variables and all mentions of the class in comments.

How exactly does that work? How does it decide what variables to rename and what to rename them to?
