Issue #5054 has been updated by Thomas Sawyer.


There are better ways to deal this, e.g.

  module MyModule
    class MyClass
      def my_method
        10.times{ p :small if rand < 0.5 }
      end 
    end 
  end

If the code gets too big for this kind of reduction, then it should probably be refactored into multiple methods.

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:

>   * expression with code chunk, e.g lambdas and blocks

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

Some implementations already exists.

Thanks for your consideration.
