hm i like that idea, but think that might be a bit conflicting, that depends on if obj is an object or not?

~~~ ruby
obj = Object.new
obj:method #=> syntax error
~~~

but notice that: (xyz not known)

~~~ ruby
xyz:method #=> undefined method 'xyz' for main
~~~

it thinks that it's `xyz(:method)`

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?
