part of #24407
I'm not sure whether I should be trying to explain the general rule in the E0210 explanation or just point people to the RFC. However, if we go with the latter option I think that the RFC will need to be revised slightly, since it is not quite as gentle as I would like.
Also, the link to RFC 1023 is not the correct one (it should be https://github.com/rust-lang/rfcs/blob/master/text/1023-rebalancing-coherence.md), but the correct one is too long. I'm aware of @michaelsproul's PR https://github.com/rust-lang/rust/pull/26290 from awhile back, but it doesn't seem to be working. Has there not been a new snapshot yet?
#27360 removed a padding field full of uint8_t's, but didn't remove
the use. This didn't get picked up presumably because (a) bors
doesn't have any BSD builders, and/or (b) #[cfg]'d out blocks don't
get linted.
```

```
this makes the second code block consistent with the first code block -- other than being in reversed order, the first code block claims b is u16 and c is u32, whereas the second code block claims the opposite. seems to be an obvious typo.
Most errors generated by resolve might be caused by
not-yet-resolved glob imports. This changes the behavior of the
resolve imports algorithms to not fail prematurally on first
error, but instead buffer intermediate errors and report them
only when stuck.
Fixes#18083
This is *mostly* reducing *my* use of *italics* but there's some other misc changes interspersed as I went along.
This updates the italicizing alphabetically from `a` to `ra`.

There are still problems in both the design and implementation of this, so we don't want it landing in 1.2.

Squashed at reviewer's request:
Add heading at the end of the introductory material
Spice up introductory paragraphs a bit
Use quotes instead of <code> for phrase
Remove "other" in "other restrictions" (it's not obvious that any other
restrictions have been mentioned)
"Default methods" is a second-level heading, but is not a subsection of
"Where clause"
Reword "Default methods" introduction: it's not the "last feature" on
this page
This includes a new example with Rectangle, instead of reusing HasArea,
because fn area would require the Mul trait, and the added complexity of
that would be better left for the Operators and Overloading chapter.
Squashed at reviewer's request: Move teaser for trait bounds to bottom
