Ruby3 Will Have Types

Hello,

   Today's biggest (most upvoted) story on Hacker News:

   Ruby3 Will Have Types [1]

   Any comments or thoughts here on ruby-talk about the breaking news?

  Here are my two cents:

  As a head start you can add the missing Bool type today :-), use the
safebool library / gem [2]

   Sorbet is a great inspiring project. Hopefully, open source soon.
FYI: sruby - that is (secure) ruby [3] - is an alternative ruby
(subset) with an alternative (optional) type annotation syntax e.g.

   Sorbet's `sig {params(x: Integer).returns(String)}`

  becomes

  `sig [Integer] => [String]` or `sig Integer => String`

Note: Since the sig is "yes, it's just (regular) ruby" code you can
create an alias for types e.g. I = Integer, S = String and than use
sig I=>S, for example.

   Cheers. Prost. Happy (type-safe) coding with ruby.
