Issue #5054 has been updated by Kurtis Rainbolt-Greene.


I'd just like to know, as someone who deals with this currently, that a lot of the examples shown here use keywords. While keywords are certainly a big part of Ruby blocks, they aren't the *only* blocks. In fact, as Ruby excels at it, there are a ton of DSLs out there that use "Block style" notation.

The `endwhile` and `endif` or `fi` solutions aren't *solutions* because they can't be used for block arguments for methods:

    method do
      method2 do
        method3 do
        end
      end
    end

Whatever solution comes, it needs to also work with block style DSLs, as they are our greatest resource.

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.
