Would love to see see either one implemented at this point. Not having an ergonomic way for functional composition is a pain.

My dream:

~~~
slug = title
  .then(&:strip)
  .then(&:downcase)
  .then(I18n:::transliterate)
  .then(Utils:::hyphenate)
  .then(Validations:::check_length)
  .tap(PostLogger:::info)
~~~

Feature #13581: Syntax sugar for method reference
https://bugs.ruby-lang.org/issues/13581#change-74822

----------------------------------------
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?
