Add regression tests for #55219 and #55241
Also another test where a duplicate-like error appears to have been
suppressed; I'm not 100% sure why this output changes, though I could
imagine that some duplicate suppression is enabled by this PR.
enforce user annotations in closure signatures
Not *quite* ready yet but I'm opening anyway. Still have to finish running tests locally.

r? @matthewjasper
This fixes `issue-28848.rs` -- it also handles another case that the
AST region checker gets wrong (`wf-self-type.rs`). I don't actually
think that this is the *right way* to be enforcing this constraint --
I think we should probably do it more generally, perhaps by editing
`predicates_of` for the impl itself. The chalk-style implied bounds
setup ought to fix this.
#45829 when a renamed import conflict with a previous import
Fix the suggestion when a renamed import conflict.
It check if the snipped contains `" as "`, and if so uses everything before for the suggestion.
Use a keyword in raw identifier example
That's a very small documentation fix. The text says "you can now use keywords as identifiers" but example didn't use a keyword and would work without raw identifiers.
Felix S. Klock II pointed out that this suggestion (introduced in
pull-request #43178 / eac74104) was being issued for one-field-struct
expected types (in which case it is misleading and outright wrong),
even though it was only intended for one-field enum-variants (most
notably, `Some`). Particularly tender-hearted code-historians may be
inclined to show mercy towards the author of #43178 on the grounds
that it's somewhat confusing that struct field definitions are given
in a type called `ty::VariantDef`.
Add a conditional to adhere to the original intent. (It would be
possible to generalize to structs, but not obviously net desirable.)
This adds a level of indentation, so the diff here is going to be
easier to read in ignore-whitespace mode (`-w`).
Resolves#55250.
The example was not as clear as it could be because it was making an assumption about the structure of the data in order to multiply the number of collection elements by the item size. This change demonstrates the idea more straightforwardly, without the calculation.
