Description

I had read that one of the new features of 2.4.0 is that Binding#irb is now a method, so I decided to test this out in a program I was working on. Here is the program

class Test
  attr_accessor :x, :y, :z
  def initialize(x, y, z)
    @x = x
    @y = y
    binding.irb
    @z = z
  end
end

a = Test.new(1, 2, 3)

And the error that I got is

binding_test.rb:6:in `initialize': undefined method `irb' for #<Binding:0x007f8562025078> (NoMethodError)
    from binding_test.rb:11:in `new'
    from binding_test.rb:11:in `<main>'

So, I thought that maybe it was an issue with running it in a constructor, so I tried the simpler invocation

binding.irb

but I had a problem with that as well, with a very similar error message

bind.rb:1:in `<main>': undefined method `irb' for #<Binding:0x007ff34984e880> (NoMethodError)
