[ruby-core:82611] [CommonRuby Feature#13581] Syntax sugar for method reference

Issue #13581 has been updated by zverok (Victor Shepelev).


Another pretty unholy idea: resemble the way Ruby docs document the methods:

```ruby
[1,2,3].map(&Math#sqrt)
%w[foo bar baz].each(&#puts)
```

Yes, it conflicts with comment syntax, but in fact, no sane person should join the comment sign immediately after non-space symbol.

And we already have parsing ambiguities like this:

* `foo -bar` → `foo(-bar)`;
* `foo - bar` → `foo.-(bar)`.

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?
