Thanks a lot, Matthias, for attacking E-needs-test Call for participation: Writing correctness tests. issues!

[matthiaskrgr]

I wrote a small crate that adds the //^~ annotations automatically from rustc output, it speeds things up by quite a bit :)

That's really cool! :)

This notwithstanding, the reason we should use ~| is legibility and extensibility, it's harder to add or remove error annotations if there are repeated carets.

Should be easy to make your tool use ~| where possible (they don't play nicely with revisions though, take note of that).
