I seriously saw this and thought it might be the reason for the ruby-colored banner.

facepalm

We can say it's for both Christmas and Ruby relesae. :)

Nice to see "Did You Mean" suggestions flourishing across various tools now, e.g. Git too. Error messages can be a whole lot more than indecipherable jargon, even for command-line warriors.

I'm also looking forward to never writing "if foo && foo.bar" again!

Congrats and happy holidays Ruby team :).

The fact that Christmas is almost over where I am - and I saw the normal banner all day - might explain it :)

This is actually a really great release.

`&.` removes the really annoying (and slow) `try`.

And I think the string literals freezing is going to solve a lot of problems with memory allocations.

Check out this PR for Rails that covered a lot of similar performance problems created by too many string allocations.

https://github.com/rails/rails/pull/21057/files

I wish Rails 5 could go all in on Ruby 2.3.0 and frozen string literals.

Does lonely operator support safe navigation in case of method calls with params too?

    obj&.foo(1)&.bar(2)&.zoo

this is working just fine:

  nil&.+(3)&.+(5)&.-(7)

The banner is ruby red, so why not.
