So clearly the syntax sugar for method reference is something that we *will* have. Eventually if not now.
After the "let me consider", nobu implemented it with `.:` but was there ever a final word from Matz?

`obj.:method` is introduced at r66667 by #12125 and #13581.
It encourages the functional programming style in Ruby.

But this shorthand syntax is just for methods of `self` without arguments.
It causes another feature requests like #16273 (and lambda compositions like #15428).

Such features will introduce a new view of Ruby but no one illustrates the whole picture yet.
I worried about such patch work may cause a conflict with future expansion of functional programing style or a just a garbage feature.

`.:` syntax is introduced in 2.7.0 preview1, not released in production yet.
How about reverting at this time and re-introduce with a big picture.
