Endless Ruby

A very interesting feature was proposed to be added to Ruby. If you can imagine from the title - Yes! endless Ruby. But in what context? Let's see in this blog post.

Method definition in Ruby is done this way :

def some_method
# one-line method body
end 

The proposal is to allow the below syntax for method definitions

def value(args) = expression

You see, there is no end keyword hence endless.
This just applies to method definitions.

With this in place, the below examples can be considered

def hello(name) = 
  puts "Hello #{name}!"

hello('endless Ruby') #=> Hello endless Ruby!

and

def square(x) = x * x

p square(4) #=> 16

and

x = Object.new
def x.foo = "FOO"

p x.foo #=> "FOO"

I felt it would a nice thing to add, as we often write one-line methods.
