rust-analyzer has a really cute feature "highlight related". It will highlight the enclosing loop when cursor is on `break`, or the enclosing `async` when cursor is on `await`:

I'm still experimenting with UIs for live (sandboxed) evaluation of tests. I've realised that you really want to highlight the failing assertion, not just the failing test.
Feedback welcome :)
I'm experimenting with a patch-style display format for difftastic.
What do you think? Do the colours work? What about the last example, where there's only whitespace changes and the syntactic diff has nothing to highlight?
I'm adding Erlang support for difftastic! The basic diffing works, but I'm still tweaking syntax highlighting.
The grammar distinguishes between "strings" and 'atoms', but I'm not sure if I should highlight both the same way.
