Syntax: Recover on `for ( $pat in $expr ) $block` Fixes #62724 by adding some recovery: ``` error: unexpected closing `)` --> $DIR/recover-for-loop-parens-around-head.rs:10:23 | LL | for ( elem in vec ) { | --------------^ | | | opening `(` | help: remove parenthesis in `for` loop: `elem in vec` ``` The last 2 commits are drive-by cleanups. r? @estebank

2019-07-16Rollup merge of #62666 - estebank:preempt-ice, r=eddybMark Rousskov-8/+9
Cancel unemitted diagnostics during error recovery Follow up to https://github.com/rust-lang/rust/pull/62604. Use @eddyb's preferred style and catch other case of the same problem. r? @eddyb
2019-07-15Rollup merge of #62668 - goodmanjonathan:fix-62660, r=estebankMark Rousskov-1/+1
Fix #62660 If the explicitly given type of a `self` parameter fails to parse correctly, we need to propagate the error rather than dropping it and causing an ICE. Fixes #62660.
2019-07-15Auto merge of #62670 - estebank:extern-fn-with-body, r=petrochenkovbors-14/+24
Detect `fn` with a body in an `extern` block Fix #62109.
2019-07-14Auto merge of #62643 - estebank:parse-recovery-type-errs, r=petrochenkovbors-2/+4
Do not emit type errors after parse error in last statement of block When recovering from a parse error inside a block, do not emit type errors generating on that block's recovered return expression. Fix #57383.
2019-07-14Auto merge of #62638 - estebank:issue-62554, r=petrochenkovbors-17/+13
Use snippet instead of pprinting statement Fix #62554.

2019-07-05Rollup merge of #62292 - Centril:split-async-closures, r=cramertjMazdak Farrokhzad-15/+21
Move `async || ...` closures into `#![feature(async_closure)]` The `async || expr` syntax is moved out from `#![feature(async_await)]` into its own gate `#![feature(async_closure)]`. New tracking issue: https://github.com/rust-lang/rust/issues/62290 Closes https://github.com/rust-lang/rust/issues/62214. cc https://github.com/rust-lang/rust/issues/62149 r? @varkor
2019-07-05Auto merge of #62099 - Mark-Simulacrum:syntax-print-clean-2, r=eddybbors-9/+9
Remove io::Result from syntax::print Since we're now writing directly to the vector, there's no need to thread results through the whole printing infrastructure
2019-07-04Rollup merge of #62258 - petrochenkov:idclean, r=CentrilMazdak Farrokhzad-137/+77
syntax: Unsupport `foo! bar { ... }` macros in the parser Their support in expansion was removed in https://github.com/rust-lang/rust/pull/61606. Also un-reserve `macro_rules` as a macro name, there's no ambiguity between `macro_rules` definitions and macro calls (it also wasn't reserved correctly). cc https://github.com/rust-lang-nursery/wg-grammar/issues/51
