I've been rewriting how difftastic calculates hunks, and it's beginning to look good! Alignment is a crazy hard problem. Added/removed items have no corresponding item on the other side. You can't use even previous line text (see left line 219) as previous lines may not match.

A cute feature in Pharo 9: dynamic rewriting of deprecated methods! The code and runtime are so closely integrated that you can use test execution to automatically update call sites.

I'm rewriting a Rust function transform function from `&mut Foo` to `Foo -> Foo`. It might be a little slower, but ownership makes it harder to miss parts of the Foo type when I work with values.
