Bug #21321: Namespaces do not support extending mixins

• Status: Closed
• Assignee: -
• Target version: -
• Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN

[fxn (Xavier Noria)]

The program

module M
end

class C
  extend M
end

fails under a namespace with error:

'Kernel#extend': Cannot extend object with refinement (TypeError)

[fxn (Xavier Noria)]

Maybe the root cause is enabling namespaces with RUBY_NAMESPACE=1.

I don't think it's really necessary to create a separate ticket for this from #21319, is it?

[fxn (Xavier Noria)]

@mame (Yusuke Endoh) I was here till 4 AM experimenting with this feature.

To be organized, I reported different things in different tickets. These two could be related, but I don't know it. If they are, they will be closed together.

I was yesterday running a checkout from May 6. Updated the branch now and cannot repro anymore.

cannot repro anymore.

Closing then?

[fxn (Xavier Noria)]

Yes, please, and sorry for the noise.

[byroot (Jean Boussier)]

and sorry for the noise.

It's alright, even if the feature is experimental, the sooner bugs are noticed the better. So thank you for experimenting.
