When gem repl_type_completor is installed, irb --type-completor will provide better completion in IRB.

irb(main):001* [1, 2, 3].map(&:ch█
                             |:chr|

irb(main):001* [1, 2, 3].map(&:chr).each do |c|
irb(main):002*   puts c.ch█
irb(main):003> end   |c.chars |
                     |c.chomp |
                     |c.chomp!|
                     |c.chop  |
                     |c.chop! |
                     |c.chr   |

I believe this feature will provide powerful support especially to beginners, but it requires installation and setup. And what is important, you cannot activate this feature unless you know it exists.
If repl_type_completor is a bundled gem, and if IRB uses type-completor as default (https://github.com/ruby/irb/pull/1010), Ruby 3.4's IRB will provide great experience by default.

With bundler

When repl_type_completor is not added to Gemfile, fallback to regexp-based completion.
Force require: consider later.

I added repl_type_completor at https://github.com/ruby/ruby/commit/50b32a3c9206df2ec7bcb4c54a59844c27f1c144

@tompng (tomoya ishida) Can you add owner grant of https://rubygems.org/gems/repl_type_completor to me? I will not release without maintainer's approval. But I may release a new version of that gem for release process of Ruby when you and other maintainers cannot do that.

[tompng (tomoya ishida)]

Thank you. I added owner grant.
