[ruby-core:70073] [Ruby trunk - Bug #11380] Parser regression in 2.3?

Issue #11380 has been updated by Kaneko Yuichiro.


I found out that this regression is caused by 50402 (https://github.com/ruby/ruby/commit/fd0e9d2580bf757071683581d34354064c6ceb6a)

```
# prase.rb
def foo(pr, options, &blk)
  p pr.call
end

foo -> { :hello }, a: 1 do end
```

```
$  /usr/local/bin/ruby  -v
ruby 2.3.0dev (2015-04-29 trunk 50401) [x86_64-darwin13]

$  /usr/local/bin/ruby  parse.rb
:hello
```

```
$  /usr/local/bin/ruby  -v
ruby 2.3.0dev (2015-04-29 trunk 50402) [x86_64-darwin13]

$  /usr/local/bin/ruby  parse.rb
../parse.rb:5: syntax error, unexpected keyword_do, expecting end-of-input
foo -> { :hello }, a: 1 do end
```

This code works with 2.2 but causes SyntaxError with 2.3.
