Description

I noticed the following behavior change when updating my application from Ruby 3.1 to Ruby 3.2. Using the following code:

class Foo

  def try
    yield self
  end

  private

  def bar
    puts "private method bar called"
  end
end

Foo.new.try(&:bar)

Under 3.1 (ruby 3.1.6p260 (2024-05-29 revision a777087be6) [arm64-darwin23])

private method bar called
=> nil

Under Ruby 3.2 (ruby 3.2.4 (2024-04-23 revision af471c0e01) [arm64-darwin23])

(irb):4:in `try': private method `bar' called for #<Foo:0x000000010770a578> (NoMethodError)
        from (irb):14:in `<main>'
        from /Users/tatthurs/.asdf/installs/ruby/3.2.4/lib/ruby/gems/3.2.0/gems/irb-1.6.2/exe/irb:11:in `<top (required)>'
        from /Users/tatthurs/.asdf/installs/ruby/3.2.4/bin/irb:25:in `load'
        from /Users/tatthurs/.asdf/installs/ruby/3.2.4/bin/irb:25:in `<main>'
irb(main):015:0>

Is this change expected? I could not find a note in the changelog.
