Feature #5054

Updated by nobu (Nobuyoshi Nakada) over 8 years ago

Though as matz said at rubykaigi2011 ruby is a quite good language, many people hate a long sequence of `end` `end' like this: 

 ```ruby 
 module MyModule 
   class MyClass 
     def my_method 
       10.times do 
         if rand < 0.5  
           p :small 
         end  
       end  
     end  
   end  
 end 
 ``` 

 So, I'd like to propose introducing a special keyword, en(n+)d. Using this keyword, we can rewrite the above example like this: 

 ```ruby 
 module MyModule 
   class MyClass 
     def my_method 
       10.times do 
         if rand < 0.5  
           p :small 
         ennnnnd  
 ``` 

  

 I know matz's already rejected a python-style block. He wrote:

 These bad things won't occur by introducing en(n+)d. 

 Some implementations already exists.
