class VariantHash < Hash
  def respond_to_missing?(method_name, *args)
    true
  end

  def method_missing(method_name, *args, &blk)

  end

m = "foo_"
h = VariantHash.new(m => 'a')
puts h.method(m)
puts h.send(m)

Ruby 2.2.2

t.rb:14:in `method': undefined method `foo_' for class `VariantHash' (NameError)
	from t.rb:14:in `<main>'

All other versions of Ruby, including 2.4.1

I couldn't find a dup for this, trying to track down whether this was a known bug. Thank you and sorry if this is a dup. I'm coming from https://github.com/intridea/hashie/pull/443

Possibly a regression from a fix that was made for https://bugs.ruby-lang.org/issues/10985?

• Description updated (diff)
• Status changed from Open to Rejected

It works in ruby 2.2.9.

[dblock (Daniel Doubrovkine)]

Thanks nobu, indeed, I just wanted to make sure this is seen for a possible p9? patch for 2.2.2, feel free to close if this doesn't need to be backported.

[nobu (Nobuyoshi Nakada)]

It has been backported to 2.2 and released already.
As we don't release branch-from-branch, "patch for 2.2.2" doesn't make sense.
