Module Import in a Notebook

[Kerilk]

Hello,

I am experiencing an issue similar to https://github.com/SciRuby/iruby/issues/303

I made a small github repository to reproduce the issue in binder, but this also occurs on my ubuntu 21.10 using ruby v2.7.4p191.

Here is a link to the repository: https://github.com/Kerilk/test-ruby-binder And to the notebook: Module Import Notebook

Any idea of what I could be doing wrong here?

Thanks

@Kerilk Thank you for reporting this issue. I confirmed that it is a bug that occurs only Ruby < 3.0. I'll fix it in the next version.

mrkn@mrkn-ubuntu2004:~/src/github.com/sciruby/iruby$ cat test.rb
module M
end

o = Object.new
o.extend M

o.define_singleton_method(:include) do |*args|
  M.include(*args)
end

module Foo
  def bar
    puts "baz"
  end
end

o.include(Foo)
o.bar
