// ignore-tidy-linelength

// The problem in #66357 was that the call trace:
//
// - parse_fn_block_decl
// - expect_or
// - unexpected
// - expect_one_of
// - expected_one_of_not_found
// - recover_closing_delimiter
//
// ended up bubbling up `Ok(true)` to `unexpected` which then used `unreachable!()`.

//~| ERROR expected one of `&`, `(`, `)`, `-`, `...`, `..=`, `..`, `[`, `_`, `box`, `const`, `mut`, `ref`, `|`, identifier, or path, found `*`
Introduce `#![feature(half_open_range_patterns)]`. This feature adds `X..`, `..X`, and `..=X` patterns. 2019-12-11 03:04:34 -06:00			`// ignore-tidy-linelength`
