even shorter way to do this ? `helloworld = object.new; def helloworld.hello = "hello, world!"` in ruby

In Ruby, you can use the OpenStruct class to create a short and concise way to define an object with a single property.

Here's an example:

main.rb
require 'ostruct'
helloworld = OpenStruct.new(hello: "Hello, world!")

puts helloworld.hello
93 chars
5 lines

This code creates a new object helloworld using OpenStruct with a single property hello set to the string "Hello, world!". You can then access the value of hello property using helloworld.hello.

This approach allows you to define objects with properties using a more compact syntax, avoiding the need for defining a separate class and methods. However, keep in mind that OpenStruct has some performance trade-offs compared to defining a custom class.
