I agree completely. Please don't do this. It will make code harder to maintain. With the nested ends it is visually clear if all ends are balanced, it is explicit and easier to keep in sync after changes.

Feature #5054: Compress a sequence of ends

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

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:

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.

Thanks for your consideration.
