Issue #13691 has been updated by nobu (Nobuyoshi Nakada).


Because of the precedence, `{}` is bound to `%i()` here, and `%i()` literal cannot be a method call.

----------------------------------------
Bug #13691: Word- and symbol array literals not valid where regular array is
https://bugs.ruby-lang.org/issues/13691#change-65931

* Author: ted (Ted Johansson)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin16]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
Not sure if this is a limitation of the design space in the parser, or just a missed edge case. (Note that a regular array literal works fine.)


**Steps to reproduce:**

Run ruby -c on:

~~~ ruby
hoge %i(a b) { piyo }
~~~

**Expected behaviour:**

Syntax OK

**Actual behaviour:**

~~~
syntax error, unexpected '{', expecting end-of-input
~~~
