----------------------------------------
Bug #12352: New hash syntax broken for numeric keys
https://bugs.ruby-lang.org/issues/12352

* Author: Adriano Mitre
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
[[Matz himself showed in RubyConf 2015 the following example]](https://www.youtube.com/watch?v=LE0g2TUsJ4U&t=13m04s):

~~~
h = { 1: 2, 2: 4, 3: 6 }
~~~

Which gives

~~~
SyntaxError: unexpected ':', expecting =>
h = { 1: 2, 2: 4, 3: 6 }
        ^

~~~

but which should give identical results to

~~~
>> h = { 1 => 2, 2 => 4, 3 => 6 }
=> {1=>2, 2=>4, 3=>6}
~~~
