Previously if someone wrote an enum containing:
- `A` (untagged)
- `B` (tagged)
- `C` (tagged)
- `D` (untagged)
- `E` (tagged)
- `F` (untagged)
serde_derive would produce errors referring to B and E only, saying
you're supposed to put untagged variants at the end. The choice of B and
E for this error doesn't make a lot of sense because in order to resolve
the issue, the user must either:
- move A and D down
or:
- move B, C, and E up.
This commit changes the error to appear on A and D instead.
The following changes are included:
- Delete per-file license notices at the top of each file.
- Delete the first paragraph of LICENSE-MIT (an inaccurate
pseudo-copyright line), leaving only the text of the MIT license.
Nothing about the license of Serde code has changed, only our
understanding of how to correctly communicate that license has changed.
This mirrors an equivalent change being applied in the rust-lang/rust
repository.
