should close #10549 # Description this PR is twofold - uses `to nuon --raw` in the error messages to make sure #10549 is solved and makes a difference between `"1"` and `1` - tries to introduce slightly better errors, i.e. by putting left / right on new lines => this should hopefully help when the values become a bit big 😋 # User-Facing Changes the original issue: ```nushell > assert equal {one:1 two:2} {one:"1" two:"2"} Error: × Assertion failed. ╭─[entry #3:1:1] 1 │ assert equal {one:1 two:2} {one:"1" two:"2"} · ───────────────┬─────────────── · ╰── These are not equal.
