Bug #18389

Updated by ioquatix (Samuel Williams) about 3 years ago

```ruby 
 class Foo 
   def boop 
     binding.irb 
   end 
  
   
  
	 def context 
   
	 end 
  
   
	
   def print 
   end 
 end 

 Foo.new.boop 
 ``` 

 It fails with: 

 ``` 
 > ruby ./test.rb 

 From: ./test.rb @ line 3 : 

     1: class Foo 
     2:     def boop 
  => 3:       binding.irb 
     4:     end 
     5:    
     6:  	 def context 
     7:  	 end 
     8:

 ``` 

 I suggest that `binding.irb` should be a little bit less invasive to avoid these kinds of issues.
