Subject: [ruby-core:81296] [CommonRuby Feature#13581] Syntax sugar for	method reference

Issue #13581 has been updated by americodls (Americo Duarte).


Why the version with symbol (Math->:sqrt) needs to be supported?

Feature #13581: Syntax sugar for method reference

----------------------------------------
Some another programming languages (even Java, in version 8) has a cool way to refer a method as a reference.

I wrote some examples here: https://gist.github.com/americodls/20981b2864d166eee8d231904303f24b

I miss this thing in ruby.

I would thinking if is possible some like this:

~~~
roots = [1, 4, 9].map &Math.method(:sqrt)
~~~

Could be like this:

~~~
roots = [1, 4, 9].map Math->method
~~~

What do you guys thinking about it?
