Consider these expples
{ 92 }
async { 92 }
'a: { 92 }
#[a] { 92 }
Previously the tree for them were
BLOCK_EXPR
{ ... }
EFFECT_EXPR
async
BLOCK_EXPR
{ ... }
EFFECT_EXPR
'a:
BLOCK_EXPR
{ ... }
BLOCK_EXPR
#[a]
{ ... }
As you see, it gets progressively worse :) The last two items are
especially odd. The last one even violates the balanced curleys
invariant we have (#10357) The new approach is to say that the stuff in
`{}` is stmt_list, and the block is stmt_list + optional modifiers
BLOCK_EXPR
STMT_LIST
{ ... }
BLOCK_EXPR
async
STMT_LIST
{ ... }
BLOCK_EXPR
'a:
STMT_LIST
{ ... }
BLOCK_EXPR
#[a]
STMT_LIST
{ ... }
10152: feat: Add completion for raw identifiers r=matklad a=nabakin
![rust_analyzer_pr](https://user-images.githubusercontent.com/894305/132110362-c21b713d-acaf-4a6d-9749-ff812172cbce.gif)
Adds support for valid Rust completion of raw identifiers.
Previously, code completion of fields made via raw identifiers would not re-insert those raw identifiers, resulting in invalid Rust code. Now, code completion of fields made via raw identifiers do re-insert those raw identifiers, resulting in valid Rust code.
The same is true for all code completion instances for fields and compatible Rust identifiers.

10154: feat: Complete `#![recursion_limit = "N"]` instead of `#![recursion_limit = N]` r=lnicola a=hkmatsumoto
Currently ra emits `#![recursion_limit = 128]`, but this should rather be `#![recursion_limit = "128"]`

Today, rust-analyzer (and rustc, and bat, and IntelliJ) fail badly on
some kinds of maliciously constructed code, like a deep sequence of
nested parenthesis.
"Who writes 100k nested parenthesis" you'd ask?
Well, in a language with macros, a run-away macro expansion might do
that (see the added tests)! Such expansion can be broad, rather than
deep, so it bypasses recursion check at the macro-expansion layer, but
triggers deep recursion in parser.
In the ideal world, the parser would just handle deeply nested structs
gracefully. We'll get there some day, but at the moment, let's try to be
simple, and just avoid expanding macros with unbalanced parenthesis in
the first place.

9808: fix: Look for enum variants and trait assoc functions when looking for lang items r=matklad a=Veykril
Examples for lang enum variants are the `Option` variants.
Assoc trait functions aren't being seen since they aren't declared in the direct module scope.

Fix ide_completion tests.
Move 'complete_record_literal' call to the main completion function.
Fix a rendering bug when snippet not available.
Checks if an expression is expected before adding completion for struct literal.
Move 'completion struct literal with private field' test to 'expressions.rs' test file.
Update 'expect' tests with new check in 'complete record literal'.
9764: fix: Don't use the module as the candidate node in fuzzy path flyimport r=Veykril a=Veykril
The problem was that the candidate node is whats being used for the scope, so using an inline module will yield the surrounding scope of the module instead of the scope of the module itself.
Also seems to fix the problem in this comment https://github.com/rust-analyzer/rust-analyzer/issues/9760#issuecomment-891125674, though I could not recreate that in a test for some reason.
Fixes#9760
