// 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!()`.

fn f() { |[](* } //~ ERROR mismatched closing delimiter
parser: don't use `unreachable!()` in `fn unexpected`. 2019-11-13 05:05:37 -06:00			`// The problem in #66357 was that the call trace:`
