Okay, now the "ERR" prefix becomes a bit more important because we drop
the other punctuation. I'm still not much of a fan of it, though. Makes
me wonder whether we want to take a clue from how compilers nowadays
format this, e.g. by using "pointers".
So this:
2 (
3 foo |
4 bar |
5 baz &&
6
7 fish |
8 cow ?!AMP?!
9
10 sunder
11 )
Would become this:
t/chainlint/pipe.actual:8: error: expected ampersands (&&)
7 fish |
8 cow
^
9
While this would be neat, I guess it would also be way more work than
the current series you have posted. And whether that work is ultimately
really worth it may be another question. Probably not.
So overall, I'm fine with the direction that your patch series takes.
